The English winger had become a Villains fan-favourite during his time at Villa Park, as the Birmingham outfit were his boyhood club.However, a move to City was too enticing to pass up, and the money on offer was too difficult to down. There was plenty of pressure placed on Grealish's shoulders, considering his price tag. However, he played that down when arriving at the Etihad, saying (via The Scotsman):"It don't put no pressure on me whatsoever. I take that as a compliment. I actually like it. I think it is a good tag to have."Grealish alluded to the faith he felt Manchester City had put in him by spending a club-record fee for his services:"I think when you see a football club paying that much for a player, it means they trust and value you highly and see so much potential there to work with. "I just see it as a good thing. I just hope now I can repay this whole football club by winning as many titles as possible and winning that trophy is all we want."The English winger's comments have rung true following City's treble this season. He has won two Premier League titles, the FA Cup and now the UEFA Champions League since joining the Cityzens.
