Lazio Coach Vladimir Petkovic has admitted there are 'no excuses' after his side lost 3-0 to Siena.
A brace from Innocent Emeghara and an Alessandro Rosina strike gave the Robur all three points at Stadio Artemio Franchi.
And the Biancocelesti boss has conceded that his team let the fans down in losing to the bottom of the table club.
“There are no excuses for this defeat,” he told reporters. “We have to apologize to the fans because tonight they did not see the real Lazio.
“I did not need to raise my voice at the players – they are smart and know what they have done wrong.
“I take responsibility for the team and the tactics, but you have to compliment Siena for the way they played.”
