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