Bayern Munich, helped by two record-breaking own goals and two from Michael Olise, demolished Wolfsburg 8-1 to extend their lead at the top, as the Bundesliga resumed from its winter break.

The reigning champions, who are on 44 points, 11 ahead of second-placed Borussia Dortmund, took a fifth-minute lead when Luis Díaz’s cutback was turned in by Kilian Fischer for an own goal. It was the third consecutive league game that Wolfsburg had scored an own goal, setting a Bundesliga record.

The visitors reacted well, with Dzenan Pejcinovic finishing a fine passing move that split open the Bayern defence to level in the 13th minute.

Díaz then turned scorer on the half-hour mark, heading in an Olise cross for his ninth league goal of the campaign, to put the hosts back in front. Olise is the league’s best provider with nine assists so far.

The Frenchman then got on to the scoresheet with a curled shot to bag his eighth goal of the season before hapless Wolfsburg notched up their fourth own goal in their last three league matches with Moritz Jenz putting the ball in the net from an Olise cutback.

The hosts, who also hit the post through Olise and added two more goals through substitute Raphael Guerreiro and the Bundesliga’s leading scorer, Harry Kane, in a span of 80 seconds, have never lost at home to Wolfsburg in the Bundesliga, winning 27 of 29 matches and drawing two.

Olise crowned a superb performance in his 50th Bundesliga match for Bayern by scoring his second goal of the evening in the 76th minute before substitute Leon Goretzka flicked the ball in from a tight angle late on to make it their biggest win over Wolfsburg.

“It’s not normal (for such a result), it’s not a given and we should not forget that,” Bayern’s coach Vincent Kompany said. “The first half was really not easy. But I had the feeling that when they get a bit tired, we’d create even more chances – and that’s exactly what happened in the second half.”

Christopher Nkunku scored in the 90th minute to earn Milan a 1-1 draw at Fiorentina on Sunday but, despite extending their unbeaten league run, the visitors continue to lose ground in the Serie A title race with their second stalemate in four days.

Milan remain second on 40 points, two behind Inter, who could increase their lead when they host Napoli later on Sunday, while Fiorentina are third bottom on 14 points.

“I’m not thinking about it [Inter v Napoli] at all,” the Milan manager, Massimiliano Allegri, told Dazn. “We have to think about ourselves, we have to return to winning ways, there are a lot of points still to play for.”

Milan’s only league loss this season came on the opening day and after struggling once more against a relegation-battling side – they also came from behind in Thursday’s 1-1 draw with Genoa – have gone 18 matches without defeat.

Allegri left Luka Modric, Rafael LeĂŁo and Adrien Rabiot on the bench, giving Niclas FĂŒllkrug and Ardon Jashari their first league starts, with FĂŒllkrug and Christian Pulisic looking very comfortable together up front. The pair played a neat one-two which launched Pulisic through on goal once more, this time going around David de Gea but taking the ball too far wide and his finish ended up in the sidenetting.

“We played a good first half, we had chances to score but didn’t take them,” Allegri said. In the second half Fiorentina pushed a bit more.“

Fiorentina began brightly after the break, Dodo’s deflected shot looping over the bar and Mike Maignan gathering Robin Gosens’s header from the resulting corner.

Fiorentina hit the front in the 66th minute from a corner, Pietro Comuzzo rising unchallenged and his glancing header finding the net off the far post. The hosts had failed to win in their opening 15 league games but have shown signs of recovery of late and came close to a third successive home win.

Nkunku, on as a substitute, timed his run to get on the end of Youssouf Fofana’s ball and fired past De Gea from a wide angle.
