† Appearances (Goals).
Born in Marktredwitz, West Germany, Ersen started playing in 1. FC Nuremberg, his Bundesliga input consisting in 20 minutes in a 0–1 loss at SC Freiburg, in 1998–99. After that sole season he switched to Turkey, going on to represent Beşiktaş JK, Siirtspor, Göztepe AS, Denizlispor and Ankaraspor.
In 2006–07, Ersen represented Trabzonspor, finishing the season as the league's eighth best-scorer and helping his side finish fourth, good enough for qualification to the UEFA Cup. Subsequently, he had everything arranged with La Liga outfit Recreativo de Huelva in August 2007, but the deal eventually collapsed and he stayed at Trabzonspor; in October, FIFA stepped in and declared Ersen a player of the Spanish club – he had dual citizenship, but that status changed with 2007 changes in German laws and so, he eventually played his first season for the Andalusians as a foreign player.
On 3 February 2008, Ersen finally made his Recreativo debut, on a sour note, as Sevilla FC won 2–1 away and he was sent off for a reckless challenge, after just eight minutes as a substitute. On 27 April he got his first start and scored his first goal for Recre, also assisting Javier Camuñas in a 2–0 home win that sent Levante UD to the second division.
On 1 July 2009, Ersen signed a two-year deal with Sivasspor, ending speculation he would be joining Scotland's Heart of Midlothian. On 4 August, he netted his first competitive goal for the club, in the third qualifying round of the UEFA Champions League: on the 12th minute of the second leg against R.S.C. Anderlecht, he scored the team's first ever in the competition, in a 3–1 home win (3–6 on aggregate).
