Pierre-Emerick Aubameyang fired in a Europa League hat-trick for Borussia Dortmund on Thursday as Tottenham slipped up 2-1 in Anderlecht and new Liverpool boss Jurgen Klopp prepared for his Anfield bow.

Klopp's Liverpool drew with Tottenham last weekend and Spurs got off to a dream start in Brussels.

Danish midfielder Christian Eriksen slotted past Silvio Proto on four minutes after a fluffed clearance from Senegal international Serigne Mbodji.

But Anderlecht, who lost to the north Londoners in the 1984 UEFA Cup final, were back level before the quarter of an hour when right back Guillaume Gillet volleyed in a corner past Hugo Lloris.

The visitors had a goal disallowed on the half hour when Erik Lamela's effort was deemed offside.

Anderlecht bagged the points on 75 minutes when substitute Frank Acheampong crossed from the left for in-form Italian Stefano Okaka to charge into the box to slide the ball past Lloris despite one of his boots having fallen off.

Anderlecht moved up level with Spurs on four points in Group J topped by Monaco, 1-0 winners over Qarabag.

Klopp led Dortmund to two German titles and a Champions League final and the Bundesliga side brushed aside Azerbaijan's FK Qabala 3-1 in Baku.

Qabala had not conceded in 450 minutes of European football at the Bakcell Arena until Aubameyang opened the scoring on 31 minutes with a curling 25-metre effort.

Seven minutes later he doubled the visitors' advantage from close range, and got his third in the second half when he pounced on a loose ball after keeper Dmytro Bezotosniy produced a fine save to deny substitute Sven Bender.

Dodo got a stoppage time consolation goal for Qabala.

The win for new boss Thomas Tuchel left Dortmund top of Group C.

Italian Serie A leaders Fiorentina came unstuck 2-1 at home to Lech Poznan of Poland to leave them footing Group I.

In Rome, Lazio were down to 10-men after six minutes when Mauricio was sent off after a foul on Jorgen Skjelvik.

Despite the numerical imbalance Alessandro Matri slotted the ball home to fire the Italians into a first half lead with Felipe Andersen and Antonio Candreva completing a 3-1 defeat of Rosenborg to leave them three points clear in Group G.

Sporting Lisbon routed Albanian visitors Skenderbeu 5-1 for their first win in Group H headed by Lokomitiv Moscow, held 1-1 by Besiktas.

Among the teams playing later were Klopp's Liverpool, who host Rubin Kazan from Russia.

A disappointing 1-1 draw at home to Sion on matchday two left Liverpool with just two points from their first two Group B fixtures, but the Anfield faithful will hope the arrival of Klopp can spark an upturn in fortunes.

Rubin, bottom of the group on one point, have also changed their coach since the group stage draw was made as Valeri Chaly took over as caretaker boss from Rinat Bilyaletdinov in September after the Kazan-based side lost six of their first seven league games.
