He said that he wished we had seen more of him at the Euros."I would have believed Man City had decided about Jack well before the Euros.He's a player who can be among the top in Europe. He has a talent that you don't often see, and Pep Guardiola will make his a better player.After City activated a release clause for his Villa contract, Grealish became England's most expensive footballer after they increased their bid.Francis added, "It's sad to Aston Villa." They did everything they could to keep him. They didn't expect that this clause would be negotiated, but it did.It's a proud moment for Jack. It's a day Jack will never forget. To think that Manchester City, the best team in the nation, has decided they want you to improve them - this decision was made by the man that I consider the best coach in all of football.After leaving Birmingham in February 1979 to join Nottingham Forest, Trevor Francis was back to manage the club 17 years later.What will the fee impact on Grealish?Francis, now 67 years old, sees similarities in his move to City Ground with Grealish's 25-year-old switch to Etihad Stadium.Francis believes Grealish won't be affected by the fee size after scoring the winning goal against Malmo in the European Cup final three months after joining Forest.Francis added, "He's a very confident guy."

It was a big story and there are some similarities."I went to Nottingham Forest as the current league champions just like Man City."I was going be the best manager in First Division, Brian Clough. Jack was 25 years older than me."The difference is that I signed in February, when Forest were challenging me for three trophies."I was unable to participate in the League Cup final, or in the quarters and semi-finals for the European Cup. A strange rule prevented me from being eligible for the final. We made it and I was able to lead the goal."Jack, on the other hand, is going at a very best time possible, though many Villa fans might disagree."After breaking the British transfer record, Trevor Francis and Helen Clough joined Nottingham Forest.Trevor Francis spoke to Dan Pallett, BBC Midlands Today.
