I am excited to see the change in system with a striker like Perez.
Xhakas, Mustafi are similar/upgrade of players we already have and their impact to our play won't be as drastic as it would be of Perez.
Not to mistake this as saying Perez is a fantastic signing. I don't know about him. It's just that with Welbeck & Theo, we played some really good football, but they are either unavailable or crap, so excited to see if Perez can give that consistency.
