Celtic manager Neil Lennon makes four changes following Sunday's epic Scottish Cup final win over Hearts.

Skipper Scott Brown and defender Shane Duffy picked up knocks in a titanic battle with Hearts at Hampden, while Greg Taylor and Mohamed Elyounoussi drop to the bench.

Full-backs Jeremie Frimpong and Diego Laxalt come in, along with Ismaila Soro, while there is a rare start for striker Leigh Griffiths, who grabbed an extra-time goal and slotted home in the penalty shoot-out as Celtic completed a quadruple treble.

New Ross County boss John Hughes makes a couple of changes for his first match in over three years.

Harry Paton and Sean Kelly replace strikers Billy Mckay and Oli Shaw.

St Johnstone manager Callum Davidson makes four changes to his line-up to face Rangers.

Shaun Rooney and Callum Booth, Craig Bryson joins the midfield and Chris Kane leads the attack, with Danny McNamara pushed further forward on the left.

There's no place for Scott Tanser and Jason Kerr is suspended while Ali McCann and Stevie May drop to the bench. Former Ibrox winger Michael O'Halloran, recently having overcome a hip injury, makes the bench.

Two changes for Steven Gerrard's Rangers: Joe Aribo and Ianis Hagi return to the starting line-up; Scott Arfield and Jermain Defoe drop to the bench.

Leon Balogun, who missed the weekend win over Motherwell with a head knock, is also among the substitutes.

If someone had told Premiership new-boys Dundee United that they would be in the top half of the Premiership by Christmas they would have taken it.

Micky Mellon’s side are currently in sixth spot, and a win over Kilmarnock tonight would see them further reinforce their credentials as top six contenders.

They will go into the game in fine fettle after a hard earned draw at high flying Hibs last time out, and will be confident about their chances of avenging a 4-0 defeat at Rugby Park earlier in the campaign.

Killie have travelled to Tayside with one objective: stopping the rot.

They’re on a run of three straight defeats. In fact, with just one win in their last seven league games, it's unsurprising they currently find themselves precariously placed in ninth place - just four points above Premiership basement side Ross County.

A lack of goals will also be a concern – they haven’t found the net in any of their last three games – so, three points at Tannadice would represent a welcome early Christmas present for Alex Dyer as he looks to get his side moving in the right direction again.

Celtic: Hazard, Frimpong, Ajer, Jullien, Laxalt, Soro, Turnbull, McGregor, Christie, Griffiths, Edouard.

Substitutes: Barkas, Taylor, Bitton, Ajeti, Klimala, Rogic, Johnston, Ntcham, Elyounoussi.

Ross County: Laidlaw, Watson, Iacovitti, Morris, Reid, Draper, Vigurs, Gardyne, Paton, Kelly, Stewart.

Substitutes: Tremarco, Shaw, Mckay, Hylton, Tillson, Donaldson, Wright, Williamson, Munro.

Neil Lennon insists Celtic's challenge of overturning Rangers' 16-point lead in the Premiership title race is "not insurmountable".

With three games in hand - and the upcoming clash with the league leaders on 2 January at Ibrox on the horizon - Lennon has urged his squad to "dig deep and claw back a big deficit".

Fresh from beating Hearts in the Scottish Cup final to secure a quadruple treble, Lennon said: "We have to win the games in hand; if we do that, then we've still got a bit of work to do.

"We've got a big gap to close and we can't give too much away any more."

Borna Barisic has praised Rangers' improved strength of character and says they no longer "panic" in adversity.

Following the League Cup exit to St Mirren, Steven Gerrard's side fell behind to Motherwell at the weekend.

However, a Keemar Roofe double and Cedric Itten's header saw the league leaders secure a 3-1 victory to move 16 points clear.

"Last season and the season before when we would be 1-0 down, we'd always struggle to come back," said Barisic.

"We'd start to panic and maybe couldn't come back. But [against Motherwell on Saturday] we believed in each other, didn't panic and deserved that win.

"We again scored three goals and showed the team spirit we have and a very different character from last season."

John Hughes aims to prove his critics wrong after taking up the managerial reins at Ross County.

With County four points adrift at the foot of the Premiership table, Hughes is determined to restore their fortunes.

The 56-year-old's last, three-month spell at Raith Rovers in 2017 ended in relegation from Scotland's second tier.

"You wouldn't believe how much desire I have to try to bring success and prove one or two people wrong," said Hughes after succeeding Stuart Kettlewell.

"It's not going to be easy, I've not got a magic wand, it's all hands on deck, everybody together, one for all and all for one."

Hughes' first game in charge? Tonight's trip to Celtic Park.
