The Reds midfielder says there will be "no problems" among the squad should the forward end up staying at Anfield, indicating the club must keep hold of him to achieve its goals.
The Uruguay international has made clear his desire to leave Anfield this summer - recently denying claims of a U-turn on his future - and has been the subject of two failed bids from Premier League rival Arsenal.
Brendan Rodgers has forced the former Ajax front man to train alone after a perceived lack of respect shown to the club, but the midfielder insists his teammates will be more than happy to see the wantaway forward remain on Merseyside this season.
“Of course we still want him to stay,” Henderson told reporters. “There will be no problems with the lads.
“We know he has been brilliant for us for the last few years, and I’m sure if he stays he will carry on doing that and it will not affect his football one little bit.
“We all know how good he is as a player. To achieve what you want to achieve, you’ve got to keep your best players.
“If he stays and we can keep him, that would be brilliant news. His overall game is unbelievable, really."
