Martin Petrov's stay at Espanyol lasted all of six months and just eight games, none of which the Bulgarian winger started. The former Wanderer left the Reebok Stadium in January after being unhappy with his lack of game time under both Owen Coyle and Dougie Freedman, signing a six-month-long deal with Espanyol. Petrov signed for manager Javier Aguirre, who he played under in his time at Atletico Madrid. Petrov was not the only player released as Cristian Alvarez and Raul Baena were also handed their walking papers
Petrov signed a six month deal with Espanyol in hopes of finishing his career strongly in Spain but really failed to make his mark at the Estadi Cornellà-El Prat. In those six months and eight substitute appearances, Petrov played a grand total of 132 minutes, registering four shots (only one of which was on target), and assisting one goal.
After leaving Bolton, Petrov fired shots in a video interview, saying he regretted signing for Wanderers:
"To be honest I think it was not a good choice for me and that's the first time I say that.
"I didn't have problems there but I think it was not good for me to sign there. Some strange situations happened there but I don't want to discuss that now.
"I don't know why they were just like this with me. The managers, both manager, Owen Coyle, nothing against him personally and against new manager now.
"Every time when I show them what I can, and I know exactly what I can do on the pitch, especially in the Championship now, they tell me I don't have a place to play. Sorry, but I can't accept that."
