Napoli beat Udinese 2-1, but will have to do without suspended Victor Osimhen and Amir Rrahmani for the showdown with Atalanta.
The Nigeria international striker bagged a brace to overturn the Gerard Deulofeu opener at the Stadio Diego Armando Maradona this afternoon.
However, he also received a yellow card in stoppages for handball when trying to block a shot.
That means Osimhen will be suspended for the next round in Serie A, a big clash with fifth-placed Atalanta.
Coach Luciano Spalletti will also be forced to reshuffle in defence when visiting Bergamo, because Rrahmani was booked too and he will sit out a ban as well.
Andrea Petagna is out injured for circa a month, so Dries Mertens is the only available striker to fill in.
Osimhen has scored each of Napoli’s last four Serie A goals.
