#4 Alex Sandro
The Brazilian defender has been targeted by Manchester United in order to improve their back line. He has delivered fantastic performances for Juventus in the Serie A. According to CaughtOffside, Manchester United has agreed personal terms with Sandro over a deal to bring him from Turin to The Theater of Dreams but the deal hasn't materialized due to the asking price.
Manchester United wants to sell Luke Shaw to make room and budget to rope in the left back. But reportedly, Luke Shaw has rejected a contract offered by Everton for unknown reasons. It was widely expected that he would accept the deal so that he could get a lot more game time.
If Luke Shaw accepts a deal with another club, Sandro could be headed towards United as Juventus also want to offload him, in order to make room for Marcelo.
