Celtic starlet Jacob Donnelly has signed a pre-contract with the Scottish champions ahead of penning a professional deal.

The player has featured for the Hoops U18s and also been capped at youth level for Scotland.

His pre-contract agreement means the midfielder will pen a three-year deal at Parkhead next summer.

Donnelly is highly-rated and Celtic have seen off competition from several clubs down south to get his signature.

Meanwhile, Celtic coach Harry Kewell has detailed the differences of working with Ange Postecoglou and Brendan Rodgers.

The former Liverpool midfielder is in his second year at Parkhead after being brought to the club by his fellow Australian last summer.

And Kewell has detailed the key differences in terms of coaching style between both men.

Speaking to Celtic TV, he said: "You would probably expect to work with a manager for at least three to four years before there's a change.

"I've been able to work with two great managers in the space of two years, two managers who are regarded highly in the sport, but have completely different ideas.

"I enjoyed working with Ange, his ideas of football were great. He knew exactly what he wanted and the way he presented it was clear-cut.

"It wasn't even black and white, it was just straight black. There you go. That's how clear he was.

"Now, being able to work with Rodgers, it's different. In a way I see myself more like a Brendan Rodgers type of manager.

"He looks at the game in a different way, he likes to adapt certain things and make tactical changes. It's enjoyable seeing this side of it.

"It's early, we're still picking up his ideas, but they're quite clear."
