5 things we spotted at Celtic training as transfer linked star remains and Reo Hatate rocks Sunday league staple

It's a massive week for Celtic and Ange Postecoglou as they could potentially take a huge step towards the Scottish title.

But it could just so easily come crashing down as the build-up to derby day continues.

First off though there is a home clash against Dundee United to negotiate and the Terrors shouldn't be underestimated.

They hauled themselves back into the top six hunt and arrested a run of seven league games without a win when Nicky Clark pounced to down Ross County in added time.

Despite international absences and injuries aplenty however the Celtic squad has the feel good factor. It's little wonder given the amount they've endured in the past six months - only to have the chance to narrow the game between themselves and Rangers to just a single point next week.

Here's what we noticed from an upbeat session at Lennoxtown.

Gia grinning

And quite right. Giorgos Giakoumakis has two goals in a week and he's hitting a spot of form at just the right time for Celtic.

He's shown flashes since the start but against Hearts the stocky Greek was a constant nuisance and roughed up a back three that is rarely rumbled by even the league's best forwards.

Now the No.7 can continue his journey on the goal trail against Dundee United before he'll be trusted in one of the biggest derbies this city has seen for quite some time.

Adam's still about

Earlier this week brought the news that Adam Montgomery was close to being loaned out but he was still in Celtic first-team training as of Friday afternoon.

Derek McInnes' Kilmarnock are the side after him and you feel that would be a good move, especially if he gets plenty of game time.

The experience of battling for a title in the SPFL's tightest division would serve Montgomery
