He has been a regular in his national team since making his debut in January, and he featured against England in the friendly on June 1.

However he has not made sufficient competitive international appearances to satisfy the British authorities and remains a free agent after rejecting a new contract with San Juan Jabloteh.

Redknapp told the Portsmouth News: “We are still trying to get Hyland a work permit. He’s a very good young player.

“We’ve had him over for training and seen a lot of him to know what he’s all about. I think he can be a good player here.

“It has gone on for quite a while, which is a bit frustrating. It’s just about getting that work permit and then we can get him down here. We’ll just have to wait and see what happens.”
