Everton boss Martinez laments FA Cup loss
"I felt the key moment of the game was going to the second goal and we had made it a real uncomfortable game for Arsenal," he said.
"We had a great chance and, in nine out of 10 situations like that, Ross Barkley will hit the target.
"I can see why the referee gave the penalty, although I don't agree with the decision completely, because there is contact but the ball is challenged by both of the players.
"After that, we gambled a bit and the final scoreline does not reflect what happened in the game."
