Cuthbert believes Rees-Zammit is excelling after trying life in NFL.

“He is only going to benefit from coming back into rugby,” said Cuthbert.

“He has been in a high performance environment and knows exactly what it takes to play at this level.

“He has played rugby his whole life and has only been away 18 months, the game has not changed an awful lot.

“He has probably come back more experienced and professional. He was pretty laid back, but now he seems way more dedicated.

“It has probably opened his mind to a different way of seeing the game.”

Former Wales fly-half James Hook says Rees-Zammit has something his Welsh rivals don’t.

“He has that X-factor, that point of difference,” said Hook.

“You see some of the tries he scored before he left and since he has came back.

“To be fair, Wales’ back three have not done too bad with the likes of Tom Rogers, Blair Murray and Ellis Mee, but Zammit is just something a little bit different, with that little bit of class.

“He also puts people in stadiums and bums on seats.”
