Atalanta stormed to a 4-2 victory over Napoli in Serie A on Sunday, with the win sending Gian Piero Gasperini's side fourth in the standings.
There was just one shot on target in the first half as neither side could really get going, and the only drama came on the touchline when Gasperini was sent to the stands for complaining about his side not being awarded a penalty.
The hosts' Duvan Zapata got the scoring up and running in the 52nd minute with a far-post header, before Piotr Zielinski volleyed in an equaliser six minutes later.

Goals from Robin Gosens and the in-form Luis Muriel looked to have put the home side on course for a comfortable win, only for Gosens to put through his own net in the 75th minute to get Napoli back into contention.
Cristian Romero put the game to bed four minutes later, however, to put Atalanta up to fourth on 43 points, above fifth-place Lazio on goal difference and one point clear of champions Juventus, who play Crotone on Monday, in sixth.
The defeat will increase the pressure on Napoli coach Gennaro Gattuso, with Napoli now down in seventh on 40 points, three off the top four.
AS Roma were held to a 0-0 draw at Benevento in Serie A on Sunday, despite the home side having to play much of the second half with 10 men.
The visitors could not get going in the first half, creating few openings, but their task appeared to have become easier when Benevento defender Kamil Glik was sent off for two bookable offences.
Other than substitute Edin Dzeko's late header that was cleared off the line, however, Roma did not do enough to earn all three points.
Roma stayed third on 44 points, but Paulo Fonseca's side will drop to fourth if Juventus beat Crotone on Monday. Benevento stayed 15th.
