Walter Gargano was interviewed after the game against Atalanta:

“There are no explanations, we knew this was a hard field to play on. We payed for our mistakes, it’s hard to play here and Atalanta played a great game. We were tired and this effected us, after their goal they defender. The penalty? I don’t want to comment the referee but Alvarez falls before any touch, Silvestre took the ball, but the referee is human and can make a mistake. I hope we can change until next week and return to winning. We will work hard to get back from this loss.”
