Petri Pasanen (born 24 September 1980) is a Finnish former professional footballer who played as a defender. He was most comfortable as centre-back, but also played right-back and left-back as well. Pasanen began his senior career in his native Finland before moving to Ajax. He spent most of his career at Bundesliga club Werder Bremen which he represented in the UEFA Champions League in multiple seasons, and in the 2009 UEFA Cup Final. Club career FC Lahti Born in Lahti, Finland, Pasanen became a regular for local club FC Lahti during the club's promotion season in 1998. During the next two seasons he made 42 appearances for the club in Finland's Veikkausliiga. Ajax Many of Europe's top clubs had become interested in the promising Pasanen, and in the summer of 2000 he joined Dutch club Ajax. He became a regular in the Ajax defense in his first season, but his progress was halted when he broke his foot in August 2001, and had to miss most of the 2001–02 season. Next season he was a regular again as Ajax reached the quarter-finals of the UEFA Champions League. He fell out of favour at Ajax in 2003–04, and spent the second half of the season on loan at English club Portsmouth in the Premier League. Portsmouth manager Harry Redknapp was interested in purchasing Pasanen at the end of the season, but claimed Ajax's asking price was too high. Werder Bremen Pasanen was then signed by reigning German champions Werder Bremen in the summer of 2004. He became a key player for the club, helping them to a top three finish in the Bundesliga and the second round of the Champions League in each of his first two seasons at the club. Whilst at Bremen he played in the 2009 UEFA Cup Final. Red Bull Salzburg On 30 June 2011, after the end of his contract, he left Werder Bremen, and signed for Red Bull Salzburg. On 12 May 2012, Salzburg announced that they would not renew Pasanen's contract and he would be free to look for a new club during the summer. AGF Aarhus On 28 July 2012, Pasanen signed a two-year contract with Danish topflight side AGF. He scored his first goal for AGF on 10 December 2012, in a 3−3 home draw against Silkeborg.
