Inter Milan coach Walter Mazzarri admits his players are struggling to handle the tense atmosphere at the San Siro.
Inter drew 0-0 with Catania yesterday.
Mazzarri remarked: "All week the players sensed scepticism from the fans and media. These players are not accustomed to certain pressures and felt the lack of enthusiasm in the stands, as it almost felt as if we were playing in an empty stadium.
"Unfortunately, the breakthrough incident to score didn't arrive and the lads did better when the supporters were riled up a bit by going close to a goal. The atmosphere makes a difference, as anyone who played football will know.
"Our heads are not clear and therefore we don't make the right decisions and feel the pressure when making mistakes."
