CELTIC midfielder Ryan Christie says that Aberdeen and Hearts will be challenging the Old Firm clubs for the league title next season.

Rangers were promoted back to the top-flight after winning the 2015/16 Championship title, but the 21-year-old doesn't expect last year's second and third-placed sides to lose momentum.

Christie, who joined the Hoops last summer but spent the first half of the season back at Inverness Caley Thistle on loan, also expressed his excitement at working under new manager Brendan Rodgers.

"Having the Old Firm game back is only going to be a positive thing for the league and attract a lot of attention.

"But I wouldn't say it is just between us and Rangers. Aberdeen and Hearts will be looking to push on as well.

"I'm sure a lot of players will be keeping (the semi-final defeat to Rangers) in their heads but it's a new season and we'll be looking to push on.

"We're back in training on Monday and I'm hoping to hit the ground running,

"I've got no regrets coming down to Celtic because I'm very happy with the way I've progressed these last six months.

"Obviously with the way last season finished, scoring in the final game against Motherwell sent me away on my holidays in a good mood.The Herald: 20/02/16 LADBROKES PREMIERSHIP .  CELTIC V INVERNESS CT (3-0) .  CELTIC PARK - GLASGOW .  Danny Devine (left) and Celtic's Ryan Christie. (56740946)

"I got a couple of starts in the final two games of the season so it has made me more determined to kick-on this season. It made me feel like I've got a future here.

"We've got a lot of big games before the leagues starts, so it's important to impress the manager straight away.

"I've not had a chance to speak to him yet but I'm looking forward to meeting him and to see what his ideas are.

"It's a brilliant appointment. I've been really looking forward to working with him since it was announced. It just shows how big a club Celtic really are.

"My mindset going into training next week is it's like a clean slate and your job to impress him every day in training and try to get in his thoughts of the season ahead.

"The games coming up are so big that if you play well in them you have managed to put yourself in the gaffer's thoughts straight away.

"That's what I'll be looking to do and I'm sure the other lads will be too."
