Borussia Dortmund’s new signing Erling Haaland scored a sensational hat-trick in 20 minutes on his debut to help his team come from two goals down and beat Augsburg 5-3 on Saturday as the Bundesliga resumed after the winter break. The Norwegian teenager Haaland, who joined weeks ago from RB Salzburg for a reported €20m, scored his first goal with a low drive in the 59th minute, three minutes after coming on, to cut the deficit to 3-2.

Augsburg had led through a brace from Florian Niederlechner and a goal from Marco Richter. Jadon Sancho levelled for the visitors before Haaland then tapped in Dortmund’s fourth in the 70th to put them ahead.

The 19-year-old then completed a memorable hat-trick in the 79th minute to seal their win. Fourth-placed Dortmund are now on 33 points.

Bundesliga leaders RB Leipzig came back from a goal down to beat Union Berlin 3-1 thanks to three goals in the second half. Marius Bülter had given the visitors a shock lead on 10 minutes but Timo Werner’s goals on 51 and 83 minutes and Marcel Sabitzer’s on 57 minutes secured the win, putting Leipzig on 40 points. Bayern Munich, third on 33, travel to Hertha Berlin on Sunday.

Ciro Immobile scored a hat-trick as Lazio hammered Sampdoria 5-1 on Saturday to record an 11th consecutive Serie A win and move to within three points of the leaders Juventus.

The substitute Bastos added a fourth in the second half before Immobile completed his hat-trick with his second penalty of the afternoon, taking his tally of league goals for the season to 23. Karol Linetty scored a consolation goal for Sampdoria with 20 minutes remaining, but their afternoon worsened four minutes later when defender Julian Chabot was sent off for a last-man challenge.

The result leaves the capital club in third place on 45 points, one behind Inter, who travel to Lecce on Sunday, and three adrift of the leaders Juve, who host Parma.

Fiorentina moved above Napoli in Serie A and consigned coach Gennaro Gattuso to a fourth defeat in five games with a 2-0 victory at Stadio San Paolo. Goals from Federico Chiesa and substitute Dusan Vlahovic either side of half-time gave the visitors a third consecutive win in all competitions.

In La Liga Real Madrid’s win over Sevilla took them top of the league with a three-point lead over Barcelona, who face Granada at Camp Nou on Sunday evening. Fifth-placed Getafe beat Leganés 3-0 on Friday.

Atlético Madrid’s hopes of getting back into the Spanish title race faded even further with a 2-0 defeat away by struggling Eibar. The tiny Basque side, who have the smallest stadium in La Liga, took the lead in the 10th minute when Esteban Burgos stabbed home from close range at the far post after Atlético failed to properly defend a corner.

Atlético, who lost last Sunday’s Super Cup final to Real Madrid on penalties, were without captain Koke plus defenders Kieran Trippier and José Giménez and never got a grip on the game on a rainswept evening at Ipurua. Edu Exposito’s thumping shot from the edge of the area in the 90th minute sealed Eibar’s first victory in 12 top-flight games against Atlético and took them seven points clear of the relegation zone.

Atlético, meanwhile, are third on 35 points, eight behind leaders Real Madrid and five behind champions Barcelona.

Atlético midfielder Saúl Ñíguez, who had to play at left-back during the game, was scathing about his side’s performance. “We made a bad start yet again and it’s been happening a lot recently. We really struggled to get going, we lacked hunger after being on a good run. This is a tough blow for us.”
