Edy Reja refuses to offer excuses for Napoli's sudden form slide.

"On a technical level I am the only person responsible," Reja told Napoli Magazine.

"I have to scrutinise myself as well as the lads. Against Palermo I changed formation but we conceded two goals within 14 minutes.

"I tried to change the way that we were playing and I thought the system would work against the Rosanero.

"The game against Bologna is very important. I don't know if we will play well, but we must win.

"I'd like to analyse why we fell into this slump. We were playing great football and talking about the Champions League, but it shows we need to keep our feet on the ground."
