Tottenham's Erik Lamela celebrates scoring a goal during the Europa League Group C match.

Erik Lamela's outrageous goal in a big win for Tottenham illuminated the third round of Europa League group-stage matches, in which Fiorentina and Dynamo Moscow maintained their perfect starts to the competition.

In what will rank as one of the best goals seen in Europe this season, Lamela wrapped his left leg around the back of his standing leg and somehow generated enough power to fire the ball into the corner from outside the area.

"I was stunned, for two minutes I was just thinking about that goal," Tottenham defender Jan Vertonghen said. "I've seen a lot of YouTube clips but I've never seen a goal like it."

The Argentina forward's 'rabona', as the manoeuver is known in football, set Tottenham on their way to a 5-1 victory over Greek side Asteras Tripolis in Group C.

Lamela also scored a brilliant volley, while young striker Harry Kane grabbed a hat-trick at White Hart Lane before going in goal as a replacement for sent-off keeper Hugo Lloris and letting a late free kick slip through his fingers.

"I have seen him do that in training, he's got that in his locker," Kane said of Lamela. "And it's great to see it pay off in a big game."

Spurs moved to five points and are tied for first with Besiktas, which thrashed Partizan Belgrade 4-0.

On a night of mixed fortunes for Italian clubs, Fiorentina secured a third straight win in Group K by beating PAOK Salonika 1-0 through Juan Vargas' goal, Inter Milan dropped its first points in Group F by drawing 0-0 with Saint Etienne and Napoli slipped to a first defeat in Group I, 2-0 at Swiss team Young Boys. Torino, another of Serie A's representatives, beat HJK Helsinki 2-0 to go top of Group B.
