Right Back: Dani Alves
The experienced defender signed for Pari Saint-Germain last July and he has since featured in 41 games for the French club scoring 5 times while providing 10 assists. Uncertainty surrounds his future as his current contract runs until June 2019. The Brazilian has been out of action since May and given his age (35) PSG hasn't been convinced yet to offer him a new contract.
Dani Alves hasn't ruled out a return to Barcelona while French reports argue that PSG is about to offer to him a role of liaison between the players and the administration if he decides to retire.
Left Back: Luke Shaw
The 23-year-old defender has struggled with injuries since he joined Manchester United in 2014. In fact, since his arrival at the Theater of Dreams, Shaw has missed 93 games due to injuries. As a result, the Red Devils have not offered to him a new contract yet, despite his great performances so far in the Premier League.
According to Mirror, Shaw has been heavily targeted by German club Wolfsburg, however, his desire is to remain at Old Trafford.
