Celtic: Ronny Deila targets permanent deal for John Guidetti
Ronny Deila wants striker John Guidetti to become a Celtic player permanently "as quickly as possible".
The 22-year-old Sweden international is currently on a season-long loan from Manchester City, where his contract expires in the summer.
"We're talking with everybody around him and him also, and he's positive," said the Celtic manager.
"His confidence is fantastic. At once, he was a star amongst the fans and this looks like his home."
Guidetti has scored five goals in seven games since arriving at Celtic Park.
On that subject, Deila admitted it is a "high goal" but that anything is possible.
"It's important to have high ambitions," said the manager who has now been in charge of Celtic for 20 competitive matches, winning 11 of them.
Looking ahead to Wednesday's League Cup quarter-final at home against Partick Thistle, Deila stated it is "vital" Celtic win it as they seek to secure the domestic treble.
"It's one of the three competitions we can win here in Scotland and we need to win on Wednesday if we're going to win the trophy," the Norwegian said.
"I'm looking forward to it, it's a very important game. This is the first [trophy] we can win and it's very important for me and the whole club - we'll do everything we can to do it.
"Everybody here wants to win the treble. You have to believe and if you don't believe, nothing will happen."
