Mirth premier league sometimes requires an adaptation period. Very rarely do you get a player in that's ready to go full throttle from another league from day one. We all know this. I expect Zubimendi to similarly experience or need an adaptation period.
Who am I discussing with? Your nephew nick your phone Mirth?
Edit: and if Gittens looks as good as Noni, and they were obtained for about the same price, while one already has premier league experience, why are we mad, except, again, Chelsea bins?
