Rangers sent coach Ian Durrant and scout Ewen Chester to Portugal to watch 21-year-old winger Johnson against Celtic in the Algarve Cup, as well as Cardiff's Glenn Loovens.

Southgate told the Scottish Sun: "We have not had any contact yet from Rangers but Ian Durrant is out here in Faro so maybe we can have a chat over a beer."

He added: "There are about 12 Championship clubs interested in taking Adam on loan.

"He's a great prospect but he has Stewart Downing ahead of him, so we have to see how he gets on in pre-season and make a decision.

"Adam is only 21 but he's a very good footballer. The Championship would be good for him but we had Josh Walker at Aberdeen last season and that worked out well."
