#1 Ousmane Dembele

Barcelona had signed Dembele for 105 million euros from Borussia Dortmund last season. Great expectations were laid on him as he had replaced the outgoing Neymar.
Unfortunately in his first league start against Getafe, he injured his hamstring and was ruled out for four months.
He has found it difficult to get a regular place in the Barcelona starting lineup after returning from injury. He has got abundant talent and raw pace.
He also has got the ability to track back and help his defenders. Bayern need such a winger as both Robben and Ribbery have become more injury prone with time.
Hence there is no guarantee that these players will play for most of the season. Dembele will be a good buy as with his pace he will be able to overrun the opposition and can also provide a good ball in the box for Muller.
