Serse Cosmi could not hide his delight after a successful coaching debut with Livorno following his team's 1-0 win at Roma.

Cosmi replaced sacked Gennaro Ruotolo on Wednesday and witnessed the club's first triumph of the campaign.

"We have achieved something difficult but not impossible," Cosmi said.

"In football, anything can happen."

The result lifted Livorno out of the foot of the standings.

"We have succeeded despite having to overcome adversity," Cosmi said.

"Besides Tavano's goal, we had to overcome the injury of Romano Perticone and the sending-off of Alfonso De Lucia.

"We have been lucky, something which my predecessor didn't have."

Cosmi was unimpressed with De Lucia, who picked up two yellow cards in the space of a minute.

"It has gone well for him because had we lost this game it would have been a different story," Cosmi said.

"When you are winning there is no need to get agitated.

"But they are lads. I will learn to understand them and they will learn to understand me soon enough."

Livorno take on Atalanta on Wednesday before hosting Inter Milan next weekend while Roma travel to the Friuli stadium to meet Udinese in midweek before hosting Bologna on Sunday.
