Yet Silva has confused Barça by saying that they are “an option I have, but I haven’t made a decision yet”. "I’m going to look for a team where they want me," the 31-year-old added, after Portugal beat Chile 2-1 in Lisbon. Atletico Madrid is another club that Silva has been linked to. But also lurking are Real Madrid, who are about to appoint Jose Mourinho as their new manager as announced by Perez on the campaign trail.Mourinho sees an opportunity in the market because his compatriot is free, and Silva could boost a midfield that’s struggled to deal with the losses of club legends Luka Modric and Toni Kroos in recent times.At the Bernabeu, there’s also the right wing spot which hasn’t been claimed by the likes of an injured Rodryo, or unflattering Franco Mastantuono who’s struggled to fit in since a high profile move from River Plate.In the FC Barelona squad, Lamine Yamal has that flank locked down, and Silva would instead compete for the midfield roles. Yet anyone that is having doubts about playing for the club should be forgotten about, as the great Johan Cruyff once said.
