Arsenal manager Arsene Wenger says that he does not believe that Chelsea should have been awarded a penalty in their 2-1 loss at Stamford Bridge on Saturday.
Referee Martin Atkinson pointed to the spot after Wojciech Szczesny had challenged Ramires in the area but replays showed that the Brazilian may have forced contact with the grounded stopper.
"I don't think it was a clear penalty; I think it was no penalty," he told Sky Sports. "(The referee) could have given Ramires a yellow card.
"I didn't see it well from the bench but I've been told by people have seen it on television that it is no penalty.
"If it's no penalty, it is no penalty, it's either a dive or the player has had to go down not to make contact – I don't know – all I've heard is that it doesn't look like a penalty on television."
Despite the controversy, Wenger admitted that his side did not well enough in the first period.
"For two consecutive games now we have started not on the front foot," he added. "We come into the game 2-0 down, and it's very worrying.
"Afterwards the team has given a lot but we started on the back foot again today. We were a bit unlucky as well because we did make the first chance.
"We had a great response in the second half. You can see we have quality and spirit but we have to show that for 90 minutes."
