And the Newcastle United defender could even be named captain next season.
The Dutch defender has emerged as one of the Magpies' finest stars this season - although it hasn't been hard under the circumstances.
Despite the malaise the club currently find themselves in, however, Janmaat has been a stellar performer at St James' Park - an 'outstanding' one, according to Carver.
And the Newcastle head coach has warned the club's hierarchy they must hold onto their best talent this summer, starting with Janmaat:
“You’ve got to keep your best players for as long as you can and Daryl has been outstanding,” he said. “It’s important we keep him.”
So strong is Carver's faith in the Newcastle defender, in fact, that he admits he would even be tempted to name him club captain next season (providing the 50-year-old is still in charge of the Magpies then... a doubtful outcome if his current performance is anything to go by).
Indeed, current skipper Fabricio Coloccini could be stripped of the armband, with the Newcastle boss admitting he would be 'tempted' to install Janmaat as his succesor.
Carver added: “I’d be tempted, yes, because he’s a proper leader. He’s got character, strength, he’s good around the dressing room.
“Whatever you ask him to do, he’ll do and he has a good presence around the place. He leads by example and that’s what you need a captain to do.”
From the sounds of it, Janmaat may know a thing or two about leadership more than Carver himself...
