Arsenal starlet Jack Wilshere says they cannot afford to dwell on their Champions League elimination by Barcelona.
The Gunners now have a glamour FA Cup tie at Manchester United to focus on.
"We are still in two competitions, just three points behind Manchester United in the league and with a game in hand," the 19-year-old England midfielder said.
"Maybe now that we are out of Europe, we can be stronger in the league, concentrate on that more, really push on to try to win the title.
"We know Manchester United are a great team, but they have a European game next week, so they might play a weakened side, then we can go there and take advantage of that."
Wilshere added: "We have got great mental strength, there is disappointment in the dressing room, yes, but we have got to pick ourselves up and go to Manchester United to get the win.
"Then we need to be strong now in the league, to push on and make sure we get a trophy at the end of the year.
"We want to win every game. When United come to us, we want to be in front of them, hopefully we will be."
