Sterling was superb for victory over Arsenal.
"He's a great player," insisted Henderson to liverpoolfc.com. "Defensively he works really hard for the team and going the other way he's fantastic. Scoring goals is important for any forward player and he's adding that to his game, which is brilliant.
"I think he's got every chance of going to the World Cup in the summer. He's still a young lad, but at the same time, he's mature enough and if you look at his performances, he's one of the stand-out players of the season for me.
"The way he's played in the last few weeks has been unbelievable. I'm sure the manager [Roy Hodgson] will be keeping a close eye on him."
