Ross County boss John Hughes tells BBC Sportsound pre-match: "We have to be more resolute. We lost poor goals on Saturday [against Rangers]. We can't do that tonight.

"It’s a tough, tough game. I feel Motherwell are in a false position. But they are vulnerable and we are at home.

"It's important that we start really well and let Motherwell know they are in a game. We have worked the players ever so hard."

Ross County manager John Hughes makes two alternations to the team that was beat 5-0 at Ibrox at the weekend.

Both Connor Randall and Charlie Lakin drop out the side as Jermaine Hylton comes in to face his former club along with Regan Charles-Cook.

As for Motherwell, boss Graham Alexander also makes two changes to the side that suffered a 2-0 defeat at Aberdeen on Saturday.

One is enforced as Liam Polworth serves a suspension, with Barry Maguire coming in to replace; the other change sees Christopher Long come in for Sherwin Seedorf.

After their agonising League Cup semi-final loss on Sunday, St Mirren are boosted by the return of Ryan Flynn to midfield, having been out since last February with a cruciate injury.

He is one of three changes made by manager Jim Goodwin, as Dylan Connolly drops out along with Brandon Mason, and the suspended Cameron MacPherson. Ilkay Durmus and striker Jon Obika are the players to come into the XI.

As for United, goalkeeper Benjamin Siegrist is on the bench, apparently nursing a calf injury, so Deniz Mehmet starts in goals. Lewis Neilson and Louis Appere are the other players to make way, as Luke Bolton and Marc McNulty come in to bolster the attack.

St Johnstone make two changes from the team that swept aside Hibernian 3-0 in the League Cup semi-final.Michael O'Halloran comes in for David Wotherspoon, while Craig Bryson is promoted from the bench to take the place of Ali McCann.

Scott Wright starts for Aberdeen, despite agreeing a deal to sign for arch rivals Rangers in summer, a decision that is unlikely to go down well with the club's support.The only change Aberdeen make from their 2-0 win over Motherwell is Ross McCrorie, who has returned earlier than expected from injury, coming in for Funso Ojo who is out of the squad altogether.

St Johnstone and Aberdeen is an encounter that sees two teams who must be feeling pretty good about themselves.

Saints in particular will be bristling with positivity after booking their place in the League Cup final.

And while that joy is justified, manager Callum Davidson will be keen to stress to his players that, for now, they must park any thoughts of silverware and focus solely on their Premiership campaign.

And with his side sitting ninth – and just four points off the bottom – they have plenty to occupy their minds going into the visit of the Dons.

Aberdeen returned to winning ways with an impressive win over Motherwell last time out.

It was a result which saw the Dons move back up to third, and they will be determined to stay there - something that they will be assured of if can get the three points in Perth tonight.

Steven Gerrard's Rangers side, 23 points clear of defending Premiership champions Celtic, are heading for the first title of the manager's tenure.

Tonight, they visit Hibs at Easter Road. The last time the sides met in the Scottish capital [September last year] they fought out a pulsating 2-2 draw.

What does tonight have in store?

Jeremie Frimpong has completed his move to Bayer Leverkusen for an undisclosed fee.

The 20-year-old Dutchman joined Celtic from Manchester City in September 2019 for £300,000.

"We would like to thank @JeremieFrimpong, external for his contribution to the club and wish him all the best for his future career," Celtic said.
