Motherwell manager Stuart Kettlewell tells Sportsound that striker signing Theo Bair "comes in on a significantly smaller contract than he was on at St Johnstone, so he adds real value".

"We think, given time and opportunity, he can grow into being a Premiership striker. He's not had a great deal of football, or football sessions, but we're short at the front end of the park.

"It might not be down to one player to deliver 29 goals. Part of the start is to share the goals around the club."

Here was the moment long-serving Celtic winger James Forrest unveiled the champions' flag before the match.

Celtic's player of the match David Turnbull tells Sky Sports: "It was great to be back out there, thoroughly enjoyed it.

"I'm delighted for myself and the team. Game time has been hard to come by, so it's been good to be back in there and repay the faith the manager has shown in me."

Fellow Celtic midfielder Matt O'Riley adds to that by saying his team-mate, who scored twice, is "too good not to play football".

Dundee United started their attempt to make a quick return to the top flight in devastating fashion last night with a 4-0 win away to Arbroath, but who will today suggest they could be their title challengers?

League 1 champions Dunfermline Athletic host Airdrieonians, who were runners-up behind them but started topped their Viaplay Cup group with four straight wins.

The other three fixtures all feature match-ups between sides who will have genuine promotion hopes of their own. It's going to be some league again.

Job done for Brendan Rodgers on his first game back.

Two goals for David Turnbull, one each for Kyogo and Matt O'Riley.

Ross County started really well but found themselves 3-0 down before Jordan White pulled one back with a good header.

And that Brown goal means they ended up winning the second half 2-1, something which will please Malky Mackay.

An entertaining start to the season!

Yang looks so good.

Celtic have lost Jota, but I wonder if they've got someone just as good for a fraction of the cost?

Ross Laidlaw denies James Forrest from capping a special afternoon.
