Nene was sorry to see Tintin Marquez sacked by Espanyol last week.
Mane takes charge of Espanyol today for their clash with Real Betis and Nene said: "Only the results matter. Football has these things and it is sad but one has to be prepared for this. I wish him luck because Marquez is a great person and a great coach.
"We remain confident in our work and we are supporting the new coach. The team has quality."
