Napoli live updates
Napoli coach Rafa Benitez is hoping Gonzalo Higuain can recover in time for Thursday's match at Swansea in the last 32 of the Europa League.
The Argentina striker is doubtful for the encounter at the Liberty Stadium after hurting his back in Sunday's 2-0 triumph at Sassuolo.
– Benitez speaking to www.sscnapoli.it.
Higuain sustained a knock on his back and we will have to evaluate his condition," Benitez said to www.sscnapoli.it.
It's early to evaluate whether he (will) play on Thursday or not.
Three defensive howlers helped Atalanta claim a resounding 3-0 home victory over Serie A title challengers Napoli at the Stadio Atleti Azzurri d'Italia.
Bergamo has been an inhospitable venue for Napoli over recent years and a brace from German Denis preceded Maxi Moralez's late goal to condemn the southerners to a fifth defeat from their last eight league games here.
More pressing than the fact Jose Reina, Gokhan Inler and Federico Fernandez each made glaring errors to facilitate Atalanta's goals is the fact that Napoli missed an opportunity to catch up with league leaders Juventus and second-placed Roma, who are eight and six points better off respectively.
Napoli have signed goalkeeper Mariano Andujar on a permanent transfer from Catania, the Serie A club confirmed.
The Argentinian goalkeeper will join the Naples outfit this summer, remaining on loan at Catania until the end of the season.
