Pep Guardiola has confirmed Kevin De Bruyne, Kyle Walker, Jack Grealish and Jeremy Doku all remain unavailable for Saturday's home Premier League game against Southampton.Guardiola, who named only 15 outfield players in his squad for this week’s Champions League win against Sparta Prague, also admitted he had no idea when De Bruyne would return to contention.When asked if De Bruyne and Walker were available, Guardiola said: "No, not yet."And when pressed on whether De Bruyne’s extended absence due to a thigh injury was a concern, Guardiola added: "Yes of course.
I’d prefer to have all the squad (fit) with the amount of games, but it is what it is."Hopefully he can come back soon. I don’t know (when) yet.
I would like to tell you, but I don’t know."Playmaker De Bruyne has been out since mid-September, while right-back Walker sustained a knee injury while on England duty earlier this month.Doku and fellow winger Grealish were added to City’s injured list earlier this week and missed Wednesday night’s 5-0 triumph over Sparta.When asked if either of those two would be back, Guardiola replied pointedly "no" and refused to embellish further on his latest injury woes.On a positive note, Guardiola said he had not been worried about Phil Foden after the midfielder showed encouraging signs of a return to form in midweek with City’s opening goal.Foden admitted he had suffered from 'burn-out’ after last season’s exploits with City and England earned him the Premier League player of the year award.Guardiola added: "I’m not concerned at all about how far it is (a return to top form) because I know when he is fine, he will get it.
