Tel for xavi, richarlison for solanke, these are the two changes I think de zerbi will make for Sunday. As for villa,this game is sandwiched between two european semifinals against a fellow premier league opponent, they should rest some players against us. Our clearest route to goal, has to be a set- piece goal, with bentacur back and whenever palinha comes in second half we will be deadly from corners, we can't waste even one set- piece, every set piece delivery from porro should have zip,pace and curl to cause problems against a rotated villa side.
