Lazio officials have defended Lucas Biglia following his altercation with a supporter on Saturday, while Mamadou Tounkara has also apologised for becoming involved.

Biglia had an ugly confrontation with a member of the home crowd, who reportedly spat at the Argentine midfielder, following a 1-0 Serie A loss to Chievo at Stadio Olimpico.

“We all have to give an answer to what happened,” sporting director Igli Tare said in a statement.

“Biglia is our captain.

“The boy is always the first to arrive and the last to go away from Formello, he has always behaved in an exemplary way.

“We are proud to have a player of his level at Lazio.

“I understand the anger of the fans, but it does not justify what happened to Biglia.

“We condemn the act, it is necessary to make a distinction between right and wrong.”
