#4 Neto
For the past two seasons, Valencia's first-choice keeper has been Neto, who has performed at a consistently high level for the club. However, due to a strained relationship with Marcelino Garcia, manager of Los Ches, he has been relegated to the bench - as such, he now wants out of Valencia.
Neto is a vastly underrated keeper, with excellent shot-stopping skills, and one of the best reflexes in the world. He was integral to Valencia's win in the Copa Del Rey last season, having a man-of-the-match worthy performance in the semi-final against Betis.
MARCA is reporting that a deal between the two Spanish clubs is imminent, in a swap deal with Cillessen; the Blaugrana keeper wants more gametime next season, having only played in the Copa Del Rey last season, due to Marc-Andre Ter Stegen's sublime performances in goal for Barcelona.
As a whole, this would be a very good deal for Barcelona, as Cillessen would be replaced like-for-like by another excellent goalkeeper, in a role as the club's second-choice keeper, behind Ter Stegen.
