The Premier League club will look forward to summer to strengthen their troops for next season.

People like Arsenal, Tottenham Hotspur and Manchester United have all seen many injuries in the defense this season at times, which means they can be interested in adding depth in full-back position.

Arsenal are arranged to lose Kieran Tierney and so also want a replacement, and can decide that they see the free agent market to strengthen their back line.

Manchester United really need more wing-back because they want to develop under the 3-4-3 Ruben Amorim system. And Tottenham has so many injury problems, they certainly need deeper.
