And the Celtic boss has revealed that talks with the player and his agent about a permanent move are 'going the right way.'
“I hope he will sign the contract [by the time Celtic face Inter Milan in the Europa League in February],” Deila joked, quoted as saying by the Scotsman.
“It’s going on [contract talks]. We’re talking and have an arrangement with the agent, so it’s going the right way. You never know [if it will be done by the New Year]. We’ll see. The fans should know we’re really working hard on this.”
Guidetti has impressed since joining the Bhoys on loan from Manchester City and has already struck up a rapport with supporters. The 22-year-old was ineligible for Celtic's Europa League group stages but can participate from the last 32 onwards.
