Celtic opened up a 16-point lead at the top of the Scottish Premiership by cruising to a 3-0 win over Dundee United, despite having one eye on their Champions League trip to Bayern Munich.

Brendan Rodgers made five changes from the side that lost the first leg of their play-off tie against the German giants 2-1 in Glasgow on Wednesday.

Top scorers Daizen Maeda and Nicolas Kuhn were among those to drop out, along with record signing Arne Engels.

But the defending champions took another step to a fourth consecutive title thanks to goals from Callum McGregor, Jota and Adam Idah.

Idah and Jota are in a battle to start at the Allianz Arena on Tuesday with Maeda and Kuhn certain to return against Bayern.

Jota scored his second goal since returning to the club for a second spell after ill-fated moves to Al-Ittihad and Rennes and Rodgers said he has been impressed by the Portuguese winger.

"He's shown his level since he's come back in, it's just a fitness thing really," said Rodgers.

"That's why we're managing him through those moments, so today was another chance for him to get some minutes.

"I thought him and Jeff (Schlupp) combined really well on that side, so he's getting there."

United had started the day in third place but never laid a glove on Celtic, who kept a 12th clean sheet in 13 home league games this season.

"We were hoping they would have one eye on midweek with the importance of the game, but it shows you the mentality of that group and of Brendan Rodgers as well," said the visitors' manager Jim Goodwin.

Rangers boss Philippe Clement badly needs a response from his side when they travel to Hearts on Sunday looking to cut the gap at the top.

Aberdeen climbed back into third thanks to their first win in 15 league games, 2-1 at Dundee.

The Dons opened the scoring through Kevin Nisbet and extended their lead thanks to Topi Keskinen's stunning strike.

Seb Palmer-Houlden pulled one back for the hosts but Aberdeen held on to end a club record run winless run.

Kilmarnock climbed into the top six thanks to a 3-1 win over bottom-of-the-table St. Johnstone.

Managerless Motherwell were beaten 3-0 at home by Ross County, who climb out of the relegation play-off place.
