I think ideally we need a skillfull right-footer with a good shot on him to give us a different option on the left alongside Mendy but I like Mahrez more than Zaha. Mahrez seems better in tight situations, which, with our territorial advantage, is important, and has a better long range shot - something we need to add to the squad. Also just from facing both players Mahrez has always shit me up whereas we've dealt with Zaha pretty easily.
Just a pity he isn't right footed
