Jose Mourinho today admitted Chelsea do not have the strength in depth to win the Premier League and Champions League.

Mourinho's Blues go into the weekend seven points clear of the field and favourites to overcome Galatasaray on Tuesday to move into the last eight of the European elite.

But as the Stamford Bridge boss expressed mystification at being accused of lacking respect by Manchester City midfielder Yaya Toure, he suggested he fears a double triumph will be beyond his men.

Mourinho, without David Luiz, Ashley Cole and – probably – Fernando Torres at Aston Villa tomorrow, said: ''If you ask me 'can we go all the way in the Champions League and the Premier League?' I think it's very difficult.

''Our squad is quite short. On top of that, two of our players (Nemanja Matic and Mohamed Salah) cannot play in the Champions League.

''So it's 20 minus two, which is 18, minus Van Ginkel is 17.

''That's not a huge squad in terms of numbers or experience to cope.

''Of course, it depends on what you mean by 'cope'. To cope yes. To play and do our best, yes.

''We have to 'cope' but in the meaning of 20 top players ready to change from match to match, a big turnover, five or six players from the Villa match to the Galatasary match? No, we don't have that.
