Robin van Persie is demanding Arsenal bounce back after their FA Cup semifinal defeat to Chelsea.
"We still have two targets now - that is the Champions League final and to finish fourth or even third in the league," he said.
"We are disappointed, but we need to get our stuff together and fight for the other two titles.
"We have to play the game against Liverpool on Tuesday now, whether you are happy or if you are not happy. It is the Premier League and we need those points, but I am confident because we have strong characters.
"Every experience makes you stronger, a good one and definitely a bad one.
"We have to look game by game because if you look at the schedule from now until the end of the season, it makes you a bit dizzy because we have big games every three or four days."
