Celtic coach John Kennedy isn't surprised by the transfer interest for Southampton defender Virgil van Dijk.

The Dutchman has been linked with Machester United and Manchester City.

Kennedy told the Daily Mail: "I think he's the best centre-back in England.

"Virgil is the type of player, when you look at his game and the stature of him, who could play for any team he wants to. Even Barcelona. That's the level I see him at.

"It would be stupid of some of the big teams in England not to make a move for him."
