Napoli coach Walter Mazzarri wants to be on the bench for their Champions League return-leg clash at Chelsea.
Mazzarri was handed a two-match ban for pushing Nilmar when the Villarreal player was time-wasting on the touchline.
His appeal was rejected by UEFA and he sat out the first game of the suspension when Napoli beat Chelsea 3-1 this week.
However, the Partenopei have not given up and prepared the paperwork for an appeal to the Lausanne Court of Arbitration for Sport.
