Gago insists he has not joined Roma to replace De Rossi
De Rossi is yet to open new contract talks with Roma.
"We'll see what happens in the future, I'm just here to win a first team shirt," said former Real Madrid midfielder Gago.
"Daniele De Rossi? There won't be any problems. We can co-exist in the same team, I can play anywhere in midfield.
"I had some injury problems last season and it was complicated. However, I played in the Copa America and I'm feeling good."
