Danny Mills has slammed Celtic for going public with their contract wrangle with David Turnbull while the transfer was very much alive.

Speaking exclusively to Football Insider, the ex-England international claims it was “totally wrong” for the Scottish giants to put pressure on the attacking midfielder while in transfer talks.

Motherwell announced last Wednesday that they had accepted an offer from Celtic for Turnbull but, 48 hours later, the Hoops used their Twitter account to reveal they had failed to agree terms with the player’s agent.

The treble winners took the highly unusual step of releasing a statement to state they had made Turnbull a “magnificent” offer, warning him to take it or leave it.

“Celtic have used the media to discuss transfer negotiations and it’s totally wrong,” Mills told Football Insider. “Business should be conducted privately and behind closed doors.

“Don’t get me wrong, players do the same thing, via their agents, tipping off the media about interest from other clubs, to get better deals for themselves.

“Celtic have stirred things up to get their own fans on board, it’s a bit shameful, really, and Turnbull has been dropped into a situation he didn’t want to be in. It’s a very difficult situation for a 19-year-old. 

“Celtic are a big club with a great history, and they’re a huge draw for a young Scottish player.”

Celtic’s tactics appeared to have worked because, following a stand-off over the weekend, Turnbull is now close to an agreement with the club.

This comes after he had initially settled the terms of a five-year contract last week following the agreement over a fee of around £3million.
