Wenger insists Arsenal won't lose Premier League focus
He said: "I wouldn't like to think the Premier League is less important now, we have to fight to get back into a better position.
"If we were about to play the final it would be our best chance of a trophy, but we have just won one round.
"We go to Brighton next and we will play with full power, but for us there was more at stake than just the FA Cup, it was to win again after we lost such a big game on Sunday.
"We have to try to stay in as many competitions as possible."
