Arsène Wenger later said he signed Campbell as he found that when playing against him, his attackers could not pass him like they could other players and that "it was as if he was indestructible, such a power spread from him". He made his debut for the Gunners on 18 August – the opening day of the 2001–02 Premier League season, in a 4–0 win over Middlesbrough at the Riverside Stadium. During the season, Campbell was partnered at the back by either Tony Adams (who would retire at the end of the season) or Martin Keown. He made a return to White Hart Lane during a 1–1 draw on 17 November, and though he played well, he was shocked to see his older brother Tony in the crowd supporting Spurs as the fans shouted insults out to Campbell on the pitch. Campbell enjoyed immediate success with Arsenal, as he won both Premier League and FA Cup winners' medals as Arsenal won the Double in his first season at Highbury. In the FA Cup final at the Millennium Stadium on 4 May, he played alongside Adams as the team kept a clean sheet in a 2–0 victory over Chelsea. Four days later, they secured the league title with a 1–0 victory over Manchester United at Old Trafford.
