In the meantime, Wales have struggled to repeat the form that saw them claim the 2008 Six Nations Grand Slam – winning just two of their last 13 games.

And with the Six Nations, which start in February, the last major chance to get back to winning ways before next year’s World Cup, Henson’s return would be welcomed with open arms.

But Gatland, who saw his side lose three and draw one of their autumn internationals, claims Henson will have to prove he’s back to his best before he reclaims his Wales shirt.

“I haven't spoken to him at all," said Gatland. "I'm just waiting to see him put his rugby boots on and play a game.

"I think we all know what a quality player he is. He's had some issues in the last year or so and he's made the move [to Saracens].

"For us, we just want to see him back on the field again and playing with some confidence. If he's playing, and playing well, he'd be a huge boost hopefully for the Six Nations and then for the World Cup.”

"But he's got to get his boots on and show everyone that he's able to play at the level he's capable of.

“It might take a few weeks, he thinks it's only going to take a game or two, but it might take a bit longer than that.

"If he is playing and playing well, that would give us that depth and competition. Sometimes you pick up a couple of injuries and you lack a little bit of depth.

"To get someone like Gavin back, and to get someone like Jamie Roberts back, in time for the Six Nations would be a huge boost for us.”

Henson, who joined Saracens from Ospreys in October, is set to make his long-awaited return to action against Wasps at Wembley on Boxing Day.
