Lazio are back in the Euro hunt after snatching a 2-0 win in Bergamo despite a huge injury list.
The Orobici were safe and sound, but still eager to cause problems for a Lazio side that was struggling to keep up with the Champions League race. The Biancocelesti welcomed back Senad Lulic to the line-up and Miroslav Klose on to the bench after a thigh strain in mid-March, but were without Hernanes Emiliano Alfaro, Tommaso Rocchi, Stefan Radu, Marius Stankevicius, Cristian Brocchi, Francelino Matuzalem and the suspended Federico Marchetti, Andre Dias, Cristian Ledesma and Giuseppe Biava.
Atalanta gave the gloves to 36-year-old Giorgio Frezzolini after Andrea Consigli picked up a shoulder problem, joining the injured Matteo Brighi, Guido Marilungo, Simone Tiribocchi and Daniele Capelli.
German Denis was furious on 16 minutes, as he wanted a penalty when Modibo Diakite clumsily went into a tackle from behind, but the referee controversially waved play on.
Lazio’s injury crisis deteriorated with Javier Garrido limping off following an accidental clash of heads with Ezequiel Schelotto.
The Biancocelesti thought they had scored on 24 minutes when Alvaro Gonzalez unleashed a screamer from distance that ricocheted off the underside of the crossbar and bounced back off the ground, but replays show the ball did not cross the line.
Lulic drilled just over and Lorik Cana risked an own goal with a clumsy deflection, but it was Lazio who broke the deadlock.
Libor Kozak pounced on a horrible Federico Peluso attempted clearance in the box and his angled drive was deflected in off Tomas Manfredini, leaving the goalkeeper wrong-footed.
Atalanta poured forward and defensive bodies flung themselves in the way of shots by Denis and Schelotto.
Maxi Moralez was all set to equalise from a Luca Cigarini free kick until Diakite flung himself at the shot like a human shield. Luciano Zauri also had to block Moralez after good work from Denis.
Manolo Gabbiadini’s curling free kick forced Albano Bizzarri into an acrobatic save. Atalanta got themselves down to 10 men, as Guglielmo Stendardo hit the side-netting against his former club and then sarcastically applauded the referee, earning an inevitable red card.
Lorik Cana secured the three points in stoppages, as he gathered a poor clearance and unleashed a screamer into the far top corner.
