Atletico Madrid reportedly want to bring winger Jose Callejon back to Spain but will have to give up new signing Alessio Cerci if a deal is going to happen.
Callejon caught the attention of many clubs this summer as he scored 15 goals in 37 appearances last season, with Napoli manager Rafael Benitez showing no interest in letting the 27-year-old leave.
The Spanish winger only made his move to the Serie A club last season in a £8.6m deal from Real Madrid, but Atletico will have to part with their summer signing plus cash if they want to bring Callejon back to La Liga, according to Goal.com.
Cerci, on the other hand, is still yet to play a full 90 minutes for his new employers after completing his £12m move to the Spanish champions in the summer.
Napoli have remained strong over the summer after rejecting multiple bids for Callejon, with his buy-out clause of £23m still yet to be met.
