Mundo Deportivo reports that Atletico are considering making a move for the Argentinian defender.
Atletico are keen to strengthen their defence this summer and coach Quique Sanchez Flores is keen on signing the 26-year-old.
Pareja’s contract at Espanyol is set to expire in the summer of 2012.
“I am still under contract with Espanyol and that’s all that counts for now. However, it would be difficult to turn down a team like Atletico Madrid. They are one of the best teams in La Liga and have just won the Europa League,” Pareja was quoted as saying.
