Danny Mills has accused Rangers striker Jermain Defoe of trying to “upset the apple cart” at Celtic after his comments about Eddie Howe.

Speaking exclusively to Football Insider, the ex-England and Leeds United defender delivered his verdict after Defoe opened up about his relationship with Howe when they worked together at Bournemouth.

The 38-year-old told TalkSPORT during the week he felt he was “forced out” of Bournemouth after his relationship with Howe broke down.

Howe has long been linked with the vacant manager’s position at Parkhead and this site understands he has now reached a verbal agreement to take the job.

Celtic are a club in transition and many players could be set to quit, including veteran striker Leigh Griffiths.

The Sunday Post report Aberdeen are keen on bringing the 31-year-old to Pittodrie with Scott Brown due to make the switch in the summer.

Asked if Defoe’s comments about his treatment by Howe could guide Griffiths’ future, Mills told Football Insider correspondent Connor Whitley: “I think he’ll want to meet the manager first and have a chat with him to see what the plan is.

“There may have been some other issue with Jermain Defoe.

“He’s also at Rangers so maybe he’s doing his best to upset the apple cart or doing his best to, let’s put it that way.

“I would say, the transfer window is open for quite some time in the summer, just wait. Get to know the manager and let him get to know you. Don’t be too quick to judge people, get to know them.

“Then if it doesn’t work you can leave.”
