4 – Marquinhos
The Brazilian is reportedly unhappy in Paris and could be looking to move elsewhere this summer. Widely regarded as one of the best young central defenders in world football, his price tag would be high. PSG often utilise him at right back, and although that is not his favourite position, he can be effective there. With that in mind you can see the benefit of having him in the squad, especially with Mathieu Debuchy, the clubs main back up right back, expected to leave permanently this summer – whilst Calum Chambers could be loaned out.
