You are the fool for overhyping him and trying to come up with excuses for why he’s not that great.Players often take a year to get accustomed to Pep’s way of playing. Bernardo, Gundogan, Cancelo, Mahrez - All had pretty limited opportunities in their first year before becoming key players.
Anyone writing off Grealish is a fool.
Grealish hasn’t had limited opportunities, he literally started their first game in the community shield and every game since till he got injured.
