Premier League clubs will be looking ahead to the summer to strengthen their squads for next season. 

The likes of Arsenal, Tottenham Hotspur and Manchester United have all seen a lot of injuries in defence this season at times, meaning they could be keen to add more depth at the full-back position.

Arsenal are set to lose Kieran Tierney and so will want a replacement, and may decide that they look at the free agent market in order to strengthen their back line.

Manchester United are desperately in need of more wing-backs as they look to develop under Ruben Amorim’s 3-4-3 system. And Tottenham have had so many injury issues, they certainly need more depth.
