He started the season mainly as a reserve player, though he scored his first goal for Arsenal in the club's 3–0 League Cup third round victory at Sunderland on 25 October 2005.

Despite leaving for the African Cup of Nations in January 2006, he was immediately sent into action on his return; he made his first career Premiership start at right back against Liverpool at Anfield, replacing the injured Lauren.

[citation needed] Eboué's run in the Arsenal side included matches in the UEFA Champions League knockout phase against Real Madrid, Juventus, and Villarreal.

Impressed with the way the Ivorian adapted to the increased pace of the Premiership and pressure of the Champions League, Arsenal manager Arsène Wenger even compared Eboué to the legendary Brazilian winger Garrincha after an energetic performance in the 1 April 2006 game against Aston Villa.

[5] Eboué continued in the starting line-up for Arsenal in the 2006 UEFA Champions League Final at the Stade de France.

He made his first team return as a substitute in the 1–0 defeat by West Ham United on 5 November, and started the League Cup win over Everton later that same week.

He attempted to make many comebacks, mostly against high-profile teams such as Liverpool, in the FA Cup third Round and Manchester United, but he was unable to come through them unscathed.

From the start of the 2007–08 season, Arsène Wenger stated his intention to move Eboué into a role on the right wing, following the signing of Bacary Sagna.

This dramatic dip in form also coincided with other problems in the team, notably the absence of teammate Theo Walcott (who also played regularly on the right wing) through injury.

On 9 March 2010, in the second leg of Arsenal's Champions League tie at home to Porto, Eboué scored the fourth goal in a 5–0 win having come on as a substitute.

In the following match against Liverpool at the Emirates Stadium, however, he conceded a last-minute penalty by pushing Lucas Leiva in the back which denied the club victory and left them six points adrift of the leaders.

On 16 August 2011, Eboué completed a move to Turkish club Galatasaray[10][11] for €3.5 million in 4-year contract (worth €2.35M a season plus bonus).

[12] Following his move to Galatasaray, Eboué revealed that manager Arsène Wenger told him he would have few first-team opportunities and to listen to interest to join the Turkish side.

[16][17] On 9 April 2013, in the Champions League quarter-final second leg against La Liga club Real Madrid, Eboué scored from long range as Galatarsay secured a 3–2 win, falling 5–3 on aggregate.

[28] Eboué debuted for Ivory Coast in 2004 and had generally been a regular fixture in the defence operating at right-back for the Elephants, along with former teammate Kolo Touré.

In December 2017, Eboué told the Sunday Mirror that he is poor and homeless due to his divorce and bad investments that were under his former wife's control.
