Former Chelsea midfielder Nemanja Matic is backing their move for new manager Mauricio Pochettino.
The former Tottenham and PSG manager is in LA to finalise contract terms with Chelsea's American offers.
Roma veteran Matic said: "I think so (Pochettino will need time).
"I have to say Chelsea did a great job signing so many talented players, but in the future, next season, they'll need to make some balance between experience and young players.
"When you sign six, seven or eight young top talented players they all expect to play and that is a problem.
"Some will need time to adapt to the Premier League.
"They will need six more months or one season to adapt, but during that transition the experienced players can help them.
"I think at the end of the season they'll understand what the problem was and they will try to change.
"Next season I expect Chelsea to be much better, but it is going to be very difficult."
On Pochettino, he added: "He has experience and I know he's very professional and a very honest person, so why can't he succeed?"
