New Delhi: Afghanistan coach Yousef Kargar on Sunday accused the referee of being partial towards India in their 0-4 defeat in the final of the SAFF Championship and said his country will write a letter to the Asian Football Confederation to look into the matter.

Kargar was furious after referee Sukhbir Singh from Singapore awarded a penalty to India on the 70th minute of the match, following that with a red card to goalkeeper Hamidullah Yousufzari.

"The first half we played very well, in the second half, the judgment of referee, he gave a wrong penalty. The morale of the team was killed," he told reporters at the post-match press conference.

"A young and inexperienced referee in the final, his judgement cost us the game. He is a Hindu or a Sikh and hence he supported the Indian team. We are going to write to AFC," Kargar said.

That penalty gave India an opportunity to break the deadlock, and Sunil Chhetri converted from the spot.

Moments after leading India to their sixth SAFF title, skipper Climax Lawrence was, however, sure that the referee did his job well.

"The player pushed the referee and that is an offence," Lawrence said.

Indian coach Savio Medeira felt the referee was not partial to the home side.

"I don’t think the referee was partial, maybe it was hard. They started well, the goalkeeper had kept his temper cool without hitting the referee," Medeira said.
