#3 Aleix Vidal

The Spaniard was signed when Barca was going through a transfer embargo in 2015, which did not allow them to field players which they signed that summer. As a result, he did not feature for Barca until January 2016.
Since then, he has found playing time hard to come by garnering roughly 1,200 league minutes over the past few seasons with injuries a major reason for this state of affairs.
Before he moved to Barca, he was considered to be one of the most promising full-backs in La Liga having played for Almeria and Sevilla where he contributed a total of 10 assists and 10 goals in two seasons ( not bad for a fullback).
Valencia and AS Roma are said to be considering a move for the right back. It is believed that there has been contact between the clubs and the player's agent, only the fee is to be agreed with Barca.
The move makes sense as the Blaugrana already have Nelson Semedo and Sergio Roberto who are capable of playing in his preferred position.
Vidal is still a good player and is a good option for clubs who are looking to bolster their squads.
