Chennaiyin's title defence suffered yet another blow at the Tata Sports Complex on Sunday when they were well and truly beaten by a strong Jamshedpur FC unit.
Raphael Augusto scored a consolation goal for the visitors who were overcome by goals from Pablo Morgado, Carlos Calvo and Mario Arques.
Speaking after the match, John Gregory rues silly errors by his players that lead to goals. "They started very well. They were very quick for the beginning. Scored an incredible goal. After that, they got a debatable penalty and they were 2-0 up. After that, it was impossible to come back from there.
"We played well initially. We got back into the game in the second half. Jamshedpur had a habit of giving away the lead. It happened against Kerala. We felt we could have come back even at 2-0.
"We started the second half well. Then we scored a penalty goal. But we conceded again a silly goal. This is something which is hurting us this season. We never used to give away such goals last season. But I won't blame my boys, they are working hard," the Chennaiyin FC head coach said.
"We have made defensive mistakes. There were matches where we didn't take our chances. Their (Jamshedpur) first goal was good but wasn't a genuine chance. And the third goal was again a bad goal to concede," the Englishman added after his team's sixth loss in eight games.
Chennaiyin registered their first win of the season just before the international break and enjoyed a break of more than two weeks up until Sunday's match but Gregory wasn't prepared to use the break as an excuse for his team's poor display.
"You can use it as an excuse. We cannot give any excuses. You have to be ready for each and every game. We prepared well. The boys were confident coming into this match after the win in the last game. But credit to Jamshedpur, they started better than us.
"I will never use any excuses. If Jamshedpur can keep their feet on the floor and everybody remains fit they can win the league. No one mentions about Jamshedpur but they can be a surprise contender this season," Gregory opined.
Gregory was quizzed as to his reluctance to use two strikes in the first team. He replied, "It's obviously a risk. There are not many teams who play two strikers. Bengaluru plays with Miku and Chhetri from behind. Goa plays with Coro upfront and do really well. Even Jamshedpur plays just one forward upfront. There's too much risk in playing two forwards. I have tried playing them together but it didn't necessarily work," he concluded.
