Lazio president Claudio Lotito says everyone is on trial from now until the end of the season.

"It is time the team changed its attitude and gave something back to this club which has given it a lot," Lotito said.

"Everyone is under examination, everyone is responsible, even those who believe themselves to be great champions.

"From now until the end of the championship we need a different approach, otherwise I will take unforeseen and unexpected decisions.

"I will be tough with everyone," he concluded. "Now they are all on international duty, but when they return, they will realise who Lotito really is."
