"Of course we are interested, of course he did the medical tests, but since yesterday I have not spoken to the board and maybe when I go up for a drink they will tell me that," Southampton manager Ronald Koeman told the Daily Echo.

"For sure we are interested, but I didn't hear he has signed."

Koeman also said Southampton had had a bid -- believed to be in the region of �4.5m -- rejected by Leeds for 20-year-old right-back Sam Byram.

"We lost (Calum) Chambers to Arsenal -- Byram was a player we had on the list and it's true that we had a bid for him, yes," the Dutchman said.

"What I heard was that Leeds didn't accept it."
