Celtic defender Virgil van Dijk is ready to resist a move to Premier League.
The Daily Express says Arsenal, Liverpool, Tottenham and Manchester United have been keeping tabs on the Dutch centre-half, with reports suggesting he could leave for £10m.
But Hoops boss Ronny Deila said: "He's very happy. I have spoken with him and we are very happy to keep him as well. He's a top player.
"For me, Virgil's developing now and taking steps all the time which is very important.
"I am so happy to have him. He is enjoying his football, playing well. That's positive. He is such an important player for us.
"He has learned a lot from August. It's not the first time a player has been affected. Others have been through these things as well.
"But Virgil learned from what happened in the summer and he knows that if he's good enough things will happen. This is the way he wants to do it."
