Inter Milan coach Walter Mazzarri was left frustrated with their 2-2 draw against Bologna.
Mazzarri admitted it may well be a psychological issue within the Inter squad and he has to change tack.
"It's just one of those periods where we pay the price for every single mistake. We analyse everything and correct errors in training, but we concede these strange goals. In Verona I shouted at the players at half-time to raise the adrenaline, as every now and then we lose concentration and intensity. We ended up winning.
"I regret now that tonight I told the players they were in control and to stay calm. I should've smashed up the locker room! These players need to be shaken up and have the adrenaline kept to a maximum."
