Former Manchester United midfielder Marouane Fellaini says his old team needs experienced players.
Fellaini left United in January for Shandong Luneng.
The Ole Gunnar Solskjaer regime seems committed to regenerating their squad with a younger profile of player.
But Fellaini told the Daily Mail: "Now you have a new manager, they wanted young players and that's what happens when you play with just young players - they will be up and down, up and down, that's football.
"Of course in football, you can't play with just young players, you need a mix. I think to win games, to win titles, to win big games you need experience. Of course you can win with young players but not every game."
