“We know that we are facing an important club, even if they lost to Genoa last week,” said the Coach in his Press conference.
“We must put heart and courage on to the field in order to get a good result. There are three points up for grabs and it is our duty to seek a result.
“I’ve seen my team working hard and ready for anything. We must carry on that approach from training on to a match situation, as the psychological aspect is very important.”
Maran made his return to the bench after replacement Gigi De Canio was sacked, but lost his comeback 3-0 at home to Fiorentina.
“Lucas Castro put a lot of effort in against Fiorentina, but perhaps he should’ve been more precise with the ball at his feet. It’s important he is willing to sacrifice for the team, though.”
