Chelsea interim manager Guus Hiddink says it is mathematically possible to get into the top four but the Premier League is very tough Chelsea interim manager Guus Hiddink says it is mathematically possible to get into the top four but the Premier League is very tough

Guus Hiddink wants his Chelsea players to "look in the mirror" and decide if they have the desire to sort out their season.

Hiddink showed up for his first press conference since returning to Stamford Bridge and made it clear his appointment means the players have not performed well enough.

And there was a clear challenge to a squad that delivered the Premier League title last season but lost nine times in 16 games before Jose Mourinho's sacking: find your motivation - and quickly.

He said: "I shouldn't be here, halfway into the season, because it means things aren't going well. But I am glad to be back.

"Yesterday I talked fully to the squad. I told them, things happen in football and I want them to look in the mirror, not just two seconds but longer, and see how they can contribute on the way up.

"I told them as professionals to look in the mirror and be ultra-critical. There must be desire to play. If you don't have it, knock on my door and we'll talk... briefly.

Hiddink has been appointed until the end of the season

"We have to show to ourselves, to the club and to the fans that the team has a big desire to wash away the last half year and go up to the next coming games. If we do that, the results will follow."

Hiddink admitted it is "not easy to fix" the problems at the club and stopped short of setting a target for the season.

Asked about the possibility of bridging an 11-point gap to the top four he said: "Mathematically it's possible, but this league is very tough."

And on the prospect of making signings next month he said: "The future has to be determined by whoever is in charge. Let's go into the next few games and we'll see. I know it is always open but I'd like to end that a bit now, get into the games and then we'll see what happens."

Didier Drogba sat alongside Hiddink for the weekend victory over Sunderland, and the Dutchman later said he would like Drogba to join his staff.

Asked about Drogba at the press conference he said: "I worked with Didier a while ago and he is a legend in this club.

"At this moment he is playing in Montreal but all clubs have figures who can be ambassadors, coaches, manager or whatever, and they need the opportunity to do so. They give the brand Chelsea a big image worldwide."
