Celtic boss Ronny Deila hopes to sign permanently Manchester City striker John Guidetti in January.

Deila has revealed that the club are working on a deal that could be signed off in January.

"The negotiations are going on. There is progress all the time," he said. "We will see if we can get what we want. If we do, everyone will be happy.

"But you know what you already have. And you know players like Guidetti will be better (in the future). They are young.

"That's the kind of players we want to get in so we can progress as a team and hopefully get to the level we want to be at in Europe."
