He was appointed as head coach of the Iranian football team last season but failed to meet the expectations.
Sa Pinto has been handed a four-month suspension by the Disciplinary Committee of the Football Federation of the Islamic Republic of Iran (FFIRI) after he got involved in a controversial moment in the Tehran derby last week.
The Esteghlal coach harshly criticized the referee in the final moments of the match and was shown a red card.
“This farewell is the result of serious contemplation and recent events. I hope that under different circumstances, we may unite once again for our extraordinary club. Best wishes to Esteghlal. May it continue to soar. Until we meet again,” Sa Pinto posted on his Instagram account.
