included an option for a further one-year extension. On 4 October 2006, Ooijer claimed that his move away from PSV was caused by the club having reneged on their proposed three-year extension for him and that if the club has not done so, he would have continued to play in the Eredivisie. Ooijer's debut for Blackburn was against Chelsea on 27 August 2006 at Ewood Park. The player gave away a penalty after fouling John Terry and the subsequent spot-kick was scored by Frank Lampard. Ooijer was partially to blame for a second goal when he was outpaced by Didier Drogba in the match, which finished 2–0 to Chelsea. After this troubled start, which was soon followed by an own-goal in a game against Manchester City, he slowly adapted to Premier League football to become a mainstay in the Blackburn defence. On 20 January 2007, in only his 20th league appearance for the club, Ooijer suffered a broken fibula and torn ankle ligaments after an unfortunate fall involving Bernardo Corradi during Blackburn's victory over Manchester City at the City of Manchester Stadium. The injury kept him out of the game for the remainder of his debut season in the Premier League. On 16 August 2008, on the opening day of the 2008–09 Premier League season, Ooijer scored his first goal for the club in the 94th minute of a 3–2 win over Everton. He scored his second goal for the club on 4 April 2009, notching the winning goal in a 2–1 home game against Tottenham Hotspur, a result which was critical to Rovers' survival in the Premier League. The club exercised their right to extend the original two-year contract for a further 12 months for the 2008–09 season. On 25 March 2009, Ooijer confirmed to PSV TV that he would be returning to PSV in May 2009, when his contract with Blackburn expired. Return to PSV On 21 May 2009, Ooijer agreed a one-year deal to return to PSV, bringing his stay at Ewood Park to an end. At the end of the season, his contract ended and Ooijer again left PSV. Ajax On 9 August 2010, Ooijer signed a one-year deal with Ajax, joining on a free transfer. He made his debut in a 3–0 win against Roda JC on 21 August. On 30 October, Ooijer scored his first goal for Ajax against Heracles Almelo. On 15 April
