Manchester City are in need of a squad overhaul this summer.
City began the campaign as most people’s favourites to win the Premier League title, impressively winning their first five league games of the season without conceding a goal.
However, since then City been on a downward spiral, culminating in a 1-0 home defeat to Manchester United on Sunday - their fourth league defeat in their last six matches.
Speaking to Sky Sports after the game, Carragher acknowledged the ability in City’s players but feels they no longer have the energy and desire as before, suggesting a clear-out is needed.
“They have the oldest squad in the Premier League behind West Brom, now West Brom don't play two games a week, they play once,” Carragher explained.
"This team haven't got it in them, although they are great players you can see they haven't got the legs, the energy in them now to keep going in all competitions throughout a season.
“Pep Guardiola will be watching that today. I think he would have been thinking initially he needs three or four players. I think they might need seven or eight.”
Pep Guardiola likes his teams to play a possession-based style with plenty of high pressing, intensity and movement off the ball - traits needed in a young, fresh team with lots of energy.
City, in their current state, are quite the opposite with recent showings illustrating how laboured they have become, especially out of possession with very little movement in midfield.
Aside from Sergio Aguero, David Silva, Kevin de Bruyne, Joe Hart and Vincent Kompany, the rest of City’s squad is rather dispensable and that is an obvious worry for the incoming coach.
