The 25-year-old has been in superb form for Mauricio Pochettino's charges this season, notching four times in 18 Premier League appearances.

But the Southampton captain has cooled talk of a move away from the club, and says he is enjoying his time under the stewardship of Pochettino.
"I can't express how happy I am at the club," he said. "I am so settled. Settled at home with a young child and my family live down here.
"I don't think I am too comfortable either, I get challenged week in week out playing in the Premier League. It is where you want to be as a player.
"I am delighted and as happy as I have ever been here playing for Southampton with one of the best managers in the league.
