The four players Barcelona can now negotiate with

Barcelona are now able to start negotiating with various players they have been tracking for some time. Manchester United duo Daley Blind and Ander Herrera, Arsenal's Mesut Ozil and Schalke 04's Leon Goretska are the names. Each of them finish their contract in June and Barcelona can now negotiate with them without fear of sanctions.

Herrera is one of those who have always been on the list. Man United's midfielder has improved at the club and is one of the best in his position. Ernesto Valverde also likes him, having coached him at Athletic Bilbao.

Blind, meanwhile, has good experience at Ajax and United. He can play at left-back or centre-back, with good versatility - he can also play as the pivote. Mourinho doesn't want him and is close to signing Ghoulam to replace him.

Ozil is someone Barcelona might try and sign before the summer as he can play in the Champions League and would help with their bid to win La Liga and the Champions League. If they can get rid of Arda Turan it makes Ozil a more attractive signing now. 

Finally Goretzka is an option although the deal has gone cold, as it seems he is close to signing for Bayern Munich. Other players including Alexis Sanchez, Juan Mata, Arjen Robben, Franck Ribery and Iker Casillas are also running out of contract in June.
