Manchester City striker Sergio Aguero has urged Frank Lampard to stay with the club beyond January.
The veteran midfielder is currently on loan at the Etihad Stadium, but he is due to return to parent club New York City FC in the New Year.
Lampard has impressed during his brief career at City, scoring five goals in 11 appearances in all competitions.
While the 36-year-old's future is yet to be resolved, Aguero believes that Lampard is the type of player that could help the Blues retain their Premier League title this season.
"He's been a really important player for us - a key player," the Argentine told Sky Sports News. "Whether he starts the game or comes on in the second half, he's played a really key role in most of the games he's featured in.
"It would be fantastic if he could stay - he's a Premier League legend - and it's been a real pleasure for me to line up alongside him. It's something the club will decide but if we could get him to stay longer, I think he could be the difference."
City are back in Premier League action on Wednesday night when they travel to Sunderland.
