Celtic vs Dundee United LIVE score and goal updates from the Premiership clash at Parkhead

It's another Celtic return for Martin O'Neill - and the third time around could prove to be the toughest yet.

The Hoops are now trailing both leagues leaders Hearts and Rangers in the Premiership title races after Wilfried Nancy 's disastorous 33-day tenure in the dugout.

Last week's 3-1 derby defeat at home to Rangers was the final straw for the Celtic decision-makers - and it's now down to O'Neill to rescue the club's title chances - starting with Dundee United on home turf.

Jim Goodwin's side defeated Nancy's Celtic at Tannadice back in December - but are in need of a positive result after Dundee derby defeat last week.

And amid the backdrop of fan protests and fury at the board, can the O'Neill steady the ship with a crucial win to pile the pressure on Derek McInnes' men before the clash with Dundee on Sunday?

Well, first of all - a change in formation. The Dundee United boss said ahead of the game:

He knows what it means to win games of football. He knows how to do it and he's got really good people around him as well - the likes of Shaun Maloney, Mark Fotheringham and the other guys there behind the scenes.

We have to hope that we can go there and put on the type of performance that we did here only a few weeks ago. Albeit against what we expect is going to be a different system and different personnel among it. We know how difficult a trip to Celtic Park is.

I think they'll go back to the previous way of playing under Martin, which was a back four.

Well,
