He started his career at São Paulo, where he was part of the side that won the 2005 Copa Libertadores and the 2005 FIFA Club World Cup. However, he was underutilized for São Paulo FC, having only made twelve appearances for the club, eight of those coming off the substitutes' bench.[6]

On 31 August 2006, Denílson joined English club Arsenal for a fee of £3.4 million, choosing 15 as his shirt number. Many were surprised by his transfer to Arsenal because of his lack of experience in club football.[7] He was described as "a little bit in between Tomáš Rosický and Gilberto" by Arsenal manager Arsène Wenger.[8] Denílson was included in Arsenal's 19-man squad that travelled to face CSKA Moscow in the UEFA Champions League on 17 October 2006; he was named on the substitutes bench for the match, but did not play. He had to wait until 24 October 2006 for his first-team debut, when he started a League Cup third round match against West Bromwich Albion. He was ever-present in Arsenal's 2006–07 League Cup campaign.

He made his Premier League debut for Arsenal on 30 December 2006, coming on as a substitute in a 1–0 defeat against Sheffield United at Bramall Lane.

His first goal for Arsenal came in the League Cup Third Round fixture against Newcastle United on 25 September 2007, sealing a 2–0 win.[9] The good performance and goal seemed to have secured him a long-term place at Arsenal after it was announced that he had awarded a new contract with the club on 18 October 2007. Denílson scored another long-range shot in a League Cup match against Sheffield United on 31 October 2007, netting the final goal in Arsenal's 3–0 win.[10] Denílson's first league start came on 24 November 2007 in a match against Wigan Athletic and the young Brazilian once again impressed, with Arsenal eventually winning the match 2–0 thanks to late goals from William Gallas and Tomáš Rosický. He received his first red card at Ewood Park against Blackburn Rovers in the League Cup Quarter-Finals, where he was sent off moments before extra time.

Due to the departure of many experienced players such as Mathieu Flamini, Gilberto Silva and Aliaksandr Hleb, Denílson received more playing time and partnered Cesc Fàbregas in central midfield on many occasions. He was named in the starting line-up for all of Arsenal's five competitive matches in August 2008, scoring his first Premier League goal on 30 August 2008 in their 3–0 win at home to Newcastle United at the Emirates Stadium. On 13 September 2008, he started and played the full 90 minutes against Blackburn Rovers at Ewood Park in a 4–0 victory for the Gunners and also got booked.[11] He continued to play as a regular for Arsenal through December and scored his second Premier League goal in their 3–1 away win at Bolton Wanderers on 20 September 2008.[12] With Fàbregas out for the last remaining months of 2008, he did well to fill in for the captain and was rewarded with more playing time. Denílson added a third Premier League goal of the campaign vs. Aston Villa at Villa Park in a 2–2 draw on 26 December 2008.[13] On 11 March 2009, he converted his penalty to seal a 7–6 shoot-out victory over A.S. Roma in the Champions League Round of 16 second-leg match.

Denílson in 2009

Denílson started the first match of the 2009–10 season with a powerful strike from 25 yards out to beat Everton goalkeeper Tim Howard, leading to Arsenal winning the match 6–1 at Goodison Park. A month later he signed a new five-year deal at the Emirates Stadium.[14] However, he was then diagnosed with a seemingly innocuous back injury. This, though, was not the case and he was sidelined for two months at a crucial stage of the season.[15] Denílson came back to action against Standard Liège on 23 November where he scored Arsenal's second goal with a long-range effort in their 2–0 home win. This was Denílson's 100th appearance for the club.[16] He afterward went on to score again for Arsenal against Hull City, Everton, Stoke City and West Ham United. Denílson altogether netted a sum of 6 times during that season with all these goals being long range strikes, as in the instance of a free kick upon Hull City. In the club's league campaign, Denílson was capped 28 times, with him making starts in 25 of those games. He in all scored 5 league goals for the Gunners in an eventful season where they finished third within the Premier League.[17]

Due to the emergence of teenage sensation Jack Wilshere and his own injury concerns, Denílson appeared less often in the 2010–11 season, being used mostly as a substitute starting only six Barclays Premier League matches and featuring in just 16 in total. Overall, he made 32 appearances in all competitions, 20 starts and 12 from the bench. On 19 May 2011, Denílson announced that he was set to leave Arsenal in the summer and it was reported that he wanted to return to Brazil. Arsenal finished in fourth place that season leaving them behind Manchester City in the places for automatic Champions League Qualifying.[18]

Denílson returned to former club São Paulo on loan for the 2011–12 season after confirming he was to leave Arsenal earlier in the summer.[19][20] His number 15 squad number at Arsenal was given to new signing Alex Oxlade-Chamberlain for the 2011–12 season.

Denílson was sent off twice in his first three matches, with the latter of the red cards coming after he swore at a referee. Denílson thereafter received a number of angry messages in response to his playing upon Twitter. He then in response described the fans of whom spoke adversely about then São Paulo head coach Adílson Batista as being 'very, very annoying'. Denílson also claimed that he did not mean for his comments to be taken in a negative way towards all of the fans of the club. This was followed by a row of which ensued to such a level that several supporters demanded that Denílson was never to play for São Paulo again.[21]

On 6 October, he scored his first goal whilst upon loan, a long range strike for São Paulo against Palmeiras in a Brazilian Serie A game.[22][23] Denilson was instrumental in Sao Paulo getting to the final of 2012's Copa Sudamericana where in the second leg of such Club Atlético Tigre refused to play the match in its entirety. As so Sao Paulo went on to victoriously lift the trophy with Denilson copping a winners medal altogether.[24][25]

On 3 June 2013, Denílson's agent confirmed that both Arsenal and Denílson had agreed to terminate his contract by mutual consent.[26]

On 14 June 2013, Denílson signed a four-year contract with São Paulo.[26][27] His transfer was praised by Ney Franco.[28]

He moved to Al Wahda during the summer of 2015.[29] Whilst at Al Wahda, Denilson won the UAE League Cup of 2016.[30]

On 19 July 2016, Cruzeiro announced that they signed Denílson on loan until the end of the year.[31] After only five league matches in his spell, the club stated that they would not exercise their option of buying the player.[32]

After surgery in his right knee in 2017, Denílson agreed his contract termination with Al Wahda on July of the same year.[33]

After more than two years from his last professional match and a total of three knee surgeries, Denílson was signed by Brazilian Série B club Botafogo-SP for the 2019 season.[34][35] He made his debut for the club as a substitute in the 2019 Campeonato Paulista loss against Red Bull Brasil.[36] He was released in April having made no further appearances, due to fitness issues.[37]

On August 2020 Denílson decided to come back to Europe, signing a one-year contract with the Maltese Premier League side Sliema Wanderers.[38]
