Jack Grealish explained that he was overwhelmed by his decision to leave Aston Villa in order to join Manchester City. He felt exactly as passionate about Barcelona's departure as Lionel Messi. City's 25-year-old midfielder joined City for PS100m last week in the biggest English football deal history. It was a departure from the club where he spent his entire professional career. Grealish made the move, and it was followed up by confirmations that Messi, who had spent his entire career at Barcelona, would be leaving La Liga. They were unable to fulfill a new agreement that they had reached with Messi due to "financial as well as structural obstacles". It was so hard. Grealish could make the debut in City Premier League when they face Tottenham in Sunday’s season opener. "I went back to pre-season. I did what I was told. The manager requested that I report back. So, I went back to work for a few extra days. It was evidently difficult because it was clear in my mind that I was thinking about leaving. "Everyone knows the way Messi felt at his press conference. It's the exact same way that I felt." "Before I left, at my hotel, I spoke to the team, staff, and players, and I cried a bit." 'I'm satisfied with the record fee' Grealish joined City after the Premier League champions activated Grealish’s PS100m release condition in his Villa contract. The transfer fee beat the previous record of English football held by Paul Pogba, who re-joined Manchester United after he bought PS93.25m from Juventus in 2016. Grealish said, "It doesn’t place any pressure whatsoever on me." Grealish said, "I take this as a compliment. I love it. It's an excellent tag. "I think that when a club spends this much money on a player, they are showing trust in you and they see so much potential. It was a good thing. I now hope that I can win as many titles and repay this football club." Grealish (captain at Villa) made his debut for Pep Guardiola's side in Saturday’s Community Shield loss against Leicester at Wembley. Grealish won't be able to take over the starting position at City like he did at Villa. But he is confident that his qualities will make him stand out from Riyad Marez and Phil Foden. Grealish commented, "I feel different to every player of this squad." "You've got Raheem (a winger who likes tagging in behind) and Riyad (who's a straight dribbler). Phil is the opposite. He has a bit of everything. "I feel like my contributions will be a great asset to the team. It's that purpose the manager has brought me. He says that I can play in all positions. I feel like I bring a lot. 'City moves motivated World Cup hopes' Grealish quickly established himself as a fan favorite when England reached Euro 2020 final earlier this season. However, despite being a hugely popular figure with supporters, Grealish only played in one - but five - of England’s seven matches at the tournament. Grealish says that impressing Gareth Southgate with his club football skills was key to the decision, as there is likely to be fierce competition for places on the national squad in 2022. Grealish stated that she could name up to six or seven reasons for her decision to move here. "There were quite a several in the final. "But also the World Cup, we have such talent at the National Team now - people not even going to the Euros. "I feel like performing for Man City week after week, playing in Champions League in Europe, performing the way my mind can, could give me a fantastic future with the national soccer team. I want to be in these games at World Cup and in the qualifiers.
