Barça are being forced to search for a right back, something they hadn't planned on doing. Nelson Semedo has told the club he wants to leave. He knows it'll be impossible for a side to pay his €100m buyout clause but there's interest in him, significantly from Atletico Madrid.
Semedo has shown what he's capable of this season: incredibly fast with natural defensive instincts. But he isn't incredible at bringing the ball forward and nor has he shown anything special when he's got around the opposition's box. He's no Dani Alves, the best right back in the history of Barça, who was allowed to join Juventus on a free transfer. Ever since he left the club, that position has been an issue for Barça. Short-term solutions have been the order of the day with Sergi Roberto crowbared into the side and then Semedo, who hasn't proven himself as a starter.
The idea that Semedo could leave might actually turn out to be a good opportunity. First, they'll be able to generate more funds than expected - around €50m for the Portuguese right back - and it might hand a chance to young Wague. The Senegalese full back has impressed at Barça B and that is the role the B team - and La Masia - should have: covering the losses of the first team.
Ultimately it comes down to letting anyone leave who doesn't want to be at Barça. There are plenty of players out there who dream of playing for this club. Those who aren't happy or want to join other teams, let them. Others will come and take their places.
