Marek Hamsik has urged his Napoli teammates to quickly forget about their 5-0 loss at Barcelona.
The Azzurri were crushed in Spain on Monday night in a glamour friendly against the European champions.
"We have to forget the loss against Barca because Serie A starts this weekend," noted the attacking midfielder.
"It was an honour to play at the Camp Nou though," continued the former Brescia player. "Barcelona demonstrated how well they can play they are the best side in the world."
Walter Mazzarri's team, who finished third last term, start their Serie A campaign with a home game against Genoa on Sunday.
