That is the view of former England star Chris Waddle, who believes Grealish is too peripheral a figure at City.
Waddle only believes that Grealish should stay put if City sell Kevin De Bruyne and let him play in central positions.
"I agree with Southgate's decision to leave him out, it was right," said Waddle to Betway, on Grealish not making the Euro 2024 squad.
"He played 90 minutes in the last eight games of the season, I know City are an incredible team, hard to get in, but if you want to play for England you have to be playing football.
"Grealish is a character. He's become a left-winger in his career, but Jeremy Doku has kept him out. I can see why he's left out (of the England squad) when you've got Anthony Gordon, who's played well this season, taking people on. Phil Foden has had a great season and can play there and so can Eberechi Eze.
"So I can see how Grealish has become fourth or fifth choice, you're going to take a player who will be fourth or fifth choice. He gives balance to a side but as a winger, you have to make things happen when you get that ball one-on-one.
"But I look at Jack and he cuts back at Manchester City, it's back to Rodri, back to Rodri, back to Rodri. You just think yes he gives them balance, but he's not positive enough in taking people on, and only rarely does he come inside and shoot.
"I'm not sure he's a left-winger, and probably if you sat him down and said where would you like to play I'm sure he would say in the middle or a No.10, getting involved more on the ball, playing one-twos, affecting the game more from the middle."
