Scottish champions Celtic started their season with a 6-0 win over Motherwell at Parkhead on Saturday.
The Glasgow Giants sealed their 10th Premiership title in 11 seasons at Dundee United on Wednesday and they celebrated in style, with the title party party at home.
Japanese striker Kyogo Furuhashi scored twice in the first half, on both sides of a goal by former Motherwell midfielder David Turnbull, to give Celtic a 3-0 lead at half time.
Substitute Giorgos Giacomakis completed the defeat with two goals before Portuguese winger Jota led them 4-0.
This was a powerful way for Celtic manager Ange Postecoglou to end his first season in charge, with the team winning the Australian League Cup and the Premiership and slipping 25 points behind the Rangers to four places ahead of their arch-rivals.
Elsewhere, the Rangers prepared for the crunch week by beating Scottish Cup finalists 3-1.
Before facing Jambos again at Hampden Park next Saturday, Gers’s boss rested several senior players ahead of Wednesday’s Europa League final against Eintracht Frankfurt in Seville.
Peter Herring gave Harts the lead, but Rangers sealed the victory for Van Bronckhorst’s Man before debutant Cole McKinnon took the lead at half-time with goals from Cedric Eaton and Alex Lori.
Dundee United finished fourth with a 2-1 win over Ross County in a match dominated by visiting fans.
Blair Spittal gave the county the lead in the 65th minute with a superb strike from 25 yards out, just five minutes later Nicky Clarke equalized for United from the penalty spot.
And Clarke struck again in the 89th minute to give United the victory, with fans attacking the pitch as they celebrated and one of their own players in need of medical treatment.
Earlier, the kick-off was delayed by several minutes as United fans threw beach balls, streamers and flames on the pitch.
