Arsene Wenger felt Arsenal were just as unlucky as Fulham with penalty decisions in their 3-0 win.
Fulham were incensed when the referee changed his mind about awarding them a penalty with the score at 0-0.
But Wenger said: "You have to give the referee a chance to rule the game and you just have to accept his decision.
"There were also controversial situations in Fulham's box - especially with Thierry Henry and I think that could have been a penalty as well."
Henry felt he should have had a penalty when he was tackled by Moritz Volz before Fulham's Collins John had a goal disallowed in a heated first half.
But Arsenal scored three times in the second half to wrap up their fifth straight win.
Wenger said he had sympathy with Chris Coleman's side, who had threatened to end the Gunners' unbeaten run.
"Fulham played very well and they deserve a lot of credit because they gave absolutely everything and closed us down everywhere," he said.
"You can only congratulate their attitude and organisation and it was very close.
"But at the moment we have the quality and confidence to change games."
