Looking at Mahrez, I keep thinking did we keep the least good player of Jesus, Sterling, Mahrez for our needs. He also had a huge goal tally albeit lot of those vs lesser opponents so it was kind of predictable he will have a more flat season so to say. probably wont even reach half of the goals he had last season in all comps.
Grealish, yes keeps the ball well, and thats about it, assists and goals will be really rare from him imo. hard to see how he will beat likes of Gundo, Bernardo, Foden, Mahrez, Alvarez for A+G stats over a season. he will be closer to Rodri probably than to those others.
