Chelsea will be on high alert after their former-temporary manager and current Turkey coach Guus Hiddink said that he would tender his resignation if Turkey failed to beat Austria and Belgium in upcoming Euro 2012 qualifying games.

Turkey currently are in third spot in Group A of the Euro 2012 Qualifiers behind leaders Germany and Austria after suffering an upset defeat at the hands of minnows Azerbaijan in their previous game. The poor form has pushed Hiddink to state that he would quit if his side doesn't win the two upcoming matches. The news will alert the top European clubs, including Hiddink's former club Chelsea where he won the FA Cup in a six-month spell.

''I'm trying to make a better Turkish national team,'' Hiddink said. ''If I can't do that, I'll ask the chairman to sack me. Six points from these two games is vital. If we don't get that I can offer my resignation to the chairman and then it's up to him. It will mean that I am not a successful manager.''

In 2009, Hiddink succeeded Luis Felipe Scolari as Chelsea manager and instantly turned the club's season around with an FA Cup triumph which made him a hugely popular figure at the club. His close relation to Chelsea owner Roman Abramovich could mean that the Blues are favorites to acquire his services if they decide to part with current manager Carlo Ancelotti in the summer.

It has been confirmed that Ancelotti's position will be scrutinized during the summer and Hiddink is seen as the likely successor to the Italian should he leave. Hiddink could also be offered a directorial role which will be left vacant after Frank Arnesen's exit to Hamburg which was confirmed earlier this year.
