"I apologise for my gesture, it was the wrong thing to do," said the defender after he celebrated the goal by challenging the complaining fans.
"It was instinctive and I humbly apologise. I am a passionate person and at times that means I don't think things through. We did not deserve a defeat, so at least we got a draw.
"The side is reacting well to its problems and I think we deserved the victory today. Lazio are a great squad with excellent forwards, so we are on the right track.
"I must say we cannot change everything overnight. We are reacting strongly and playing much better."
