New Chelsea signing Deco hopes Frank Lampard decides to stay at Stamford Bridge.

"I think I can be compatible with Lampard on the pitch," said Deco. "That is of course something that the trainer (Luiz Felipe Scolari) has to decide - he is in charge.

"But I have seen a lot of Chelsea games on the TV and together Frank and I can create a lot of danger for other teams."

Deco revealed that he could have been a Chelsea player four years earlier.

"I received a great offer from Chelsea because Jose Mourinho wanted me in his new project.

"I even talked with [Chelsea owner Roman] Abramovich but Porto already had agreed a deal with Barcelona and I had given my word."
