Former Arsenal defender Nelson Vivas has resigned from Argentinian club Quilmes after sensationally attacking one of their fans.
Vivas - who signed for the Gunners in 1998 from Boca Juniors before moving on to Inter Milan - leapt into the stand to hit a spectator three times after his side's game against Atletico Rafaela.
The fan was said to have been insulting the former Argentina international during the club's disappointing draw.
The managerial position was Vivas' first role in charge and took charge just earlier this season.
Former right-back Vivas spent three years in North London with Arsenal, and he regrets the incident:
"I'm not a violent person," he is quoted as saying on BBC. "But I realise that's not the image a trainer should give."
Club President Anibal Fernandez confirmed the ex-Gunner's resignation:
"He came to my office and handed in his resignation.
"He knows he put his foot in it and realises the situation is uncomfortable for the team and regrets his actions."
Whilst at Arsenal Vivas notched up 40 league appearances in three seasons, but was often benched in favour of Gunners legend Lee Dixon.
The 5ft5 defender was loaned to Celta Vigo, before moving permanently to Italy with Inter Milan.
After a few seasons in Serie A Vivas returned to Argentina and he finished his career with Quilmes - the club he has just resigned from.
He leaves the club in 16th place in Primera Division, with 14 points from 12 matches.
