The Barca right-back wants to convince the newly appointed Barca boss that he is up to the job and hopes that the club will give him a vote of confidence by not bringing in another full-back this summer, despite the club's huge interest in bringing Bellerin back to Catalonia.
The Catalan giants have been trying to negotiate a deal for Bellerin for months now but appear to have made precious little headway.
With Barca set to start their pre-season preparations, Vidal is confident that the club do not need another another right-back and hopes to take advantage of the next few days and weeks to convince Valverde that he is right.
Whilst many of Vidal's team-mates have welcomed the potential arrival of the Spanish international, the 27-year-old is not one of them and sees a move for Bellerin as 'unnecessary'.
After regaining his starting place under Luis Enrique, an ill-time ankle fracture then put the defender out of contention for a while. However, Vidal is now back fit and determined to prove his worth and in doing so he could save Barca quite a lot of money, given the eye-watering figures that Arsenal are demanding for Bellerin.
