Danny Mills admitted he wouldn’t be surprised to see Newcastle United midfielder Ki Sung-yueng return to Celtic.

Speaking exclusively to Football Insider correspondent Laura O’Leary, the former England international admitted the Hoops signing Ki seemed like a no-brainer decision for the club to make.

Football Insider recently reported that Neil Lennon was plotting a January move for the Magpies midfielder as he wants to add another central midfielder to his squad.

It is believed that the Magpies are willing to listen to offers for the 30-year-old with him having been frozen out of the first-team by Steve Bruce.

Mills explained that managers like players they can trust and if the opportunity to sign him is there, then he can envision a deal getting done.

When asked if Celtic swooping for Ki is a no-brainer for all parties involved, Mills told Football Insider: “Yeah if they can work that out.

“Managers like players they can trust, they like players they know what they’re going to get from.

“So if that’s an opportunity, the player will be happy as he’ll know the club, the manager knows he isn’t going to have issues with settling into the environment or settling into the area, all these things are comforting for the player and the club.

“And if there’s an opportunity, I wouldn’t be surprised if that happens.”

The midfield enforcer has been at St James’ Park since joining the Magpies in July 2018 from Swansea City and his current contract is set to expire at the end of the season.

Ki previously had a successful spell at Celtic in which he made 87 appearances for the club.
