Manchester United legend Gary Neville has taken a fresh swipe at Manchester City boss Pep Guardiola by calling the Spaniard's treatment of young players into question.
The Sky Sports pundit accused the ex-Barcelona coach of "publicly killing" the Sky Blues' academy prospects with recent comments he made to the media.
"Imagine being a youth coach or young player and hearing your head coach say the young players aren't good enough. Killing them publicly," Neville tweeted.
The former England international made the remarks in response to comments that Guardiola made about City prospect Phil Foden, whom Neville previously suggested was "at the wrong Manchester club".
Guardiola had replied: "My history is there. I'm not going to put young players in the squad because they are young. They will be in the squad because they have quality. I don't have problems with that.
"The club is working well in terms of the academy. There are many players with good prospects for the future. We will be patient with those guys. They are going to train with us most, or part of, the season.
"Phil Foden is going to play in the next games. He has quality to play in that team. I'm so happy to have him. He's a Mancunian, a City fan, a humble guy. He's a fighter. He looks skinny but he's a strong guy.
"I thought even the journalist in the summertime were on holidays but I realise [Neville] is not."
England U20 international Foden has played a starring role during City's pre-season and was handed a start in their 4-1 demolition of La Liga champions Real Madrid.
