Deco made a bright start after signing from Barcelona last summer for £8m, but injuries resulted in inconsistent form since the autumn.

He described last season as the worst of his career and was desperate to move away from Stamford Bridge.

Now the 31-year-old Portugal international has hinted he may stay for another two years.

"I am getting tired of Europe, but out of respect for Chelsea, I will stay on this continent a while longer," said Deco.

"I have some offers from other clubs, but if I stay at Chelsea it's important that some things change because things happened last year that I did not like.

"I have had some adaptation problems in England and I've been sidelined with several injuries."
