It would be a dream come true, but now we must think about Serie A; we want to finish the season strongly.\"Walter Mazzarri\'s men were beaten 3-1 by Atalanta on Wednesday night at home, and Cannavaro feels the San Paolo support have every right to be upset.\"On Wednesday I watched the game from the stands against Atalanta, and I must be honest in saying that I didn\'t see the usual determination from the team.\"The fans had the right to whistle at the end, as during the game I expected a greater effort.\"Our fans are a force behind us and hopefully their good feeling will return soon and we can overcome this difficult time,\" he concluded.
