Alves then suffered a serious injury as he neared his breakthrough, so fans are desperate for him to succeed.
With City supporters feeling glum over this season's relegation battle and with many already looking ahead to a campaign in the Championship next term, Alves' performances have garnered a lot of attention in the hope that he can take his place in the squad.

It seems he's played on the left wing and on the right. Where has he looked the bigger threat?
It really seems to make no difference to him. He's unfazed wherever he's been asked to play. He has a lovely, whipped cross on him and can use that to great effect on either flank.
On the right, against Plymouth, he swept a lovely, low cross across the face of goal for Yousef Salech to slide on to for ...
