Atletico Madrid fullback Javier Manquillo is being linked with a return to England.
Manquillo had a difficult year on-loan at Liverpool two seasons ago, but impressed last term in France with Olympique Marseille.
Now, the Spain U21 international is back on the radar of English clubs, with Watford and Sunderland keen.
Manquillo, 22, is also wanted back at OM before the market shuts.
The defender will be allowed to move away again by Atletico if he can find the right club.
