It’s unlikely that Alvarez will surpass Sterling’s prime but I’m comparing the current versions of the players. Alvarez definitely has the potential to be better than last season’s version of Sterling. It’s a similar case between Phillips and Fernandinho.
I wouldn't put too much pressure on Alvarez.
It's a huge step up in quality from the Argentine league to Pep's team at the top of the Premier League.
Would be like a player coming from the Championship to Pep's team.
It was hard enough for Grealish to adapt.
Give him time. He'll likely be a bit-part player next season.
