#1 - Javier Mascherano
Easily the biggest name on the list. Javier Mascherano has regularly been starting for Barcelona in recent seasons and has been combining well with Pique, however, he will not be in the squad next season.
The Argentine is in his 30's, and Valverde wants to build a team with youngsters. Marquinhos, Davison Sanchez and Aymeric Laporte are the players who are on the wish-list.
Laporte is the top priority for Valverde as he has worked with him at Athletic Bilbao. The Frenchman is also keen on joining Barcelona this summer.
Mascherano is a target for Chinese Super League sides and is reportedly considering a move there. He wants to retire at River Plate but still, has 2-3 years of top flight football left in him easily.
