Arsenal goalkeeper Bernd Leno says they need a perfect 100 per cent record for the remainder of the season to stay in the top four.
Unai Emery's men climbed up to third with a 2-0 win over Newcastle on Monday to take control of the race for the last two top four spots.
Leno said: “I think we're in a very good position but it's still a long way because the other teams will wait for our mistakes.
“We have to be focused in every game and if it's possible we need to win every game.
"Then we can get back to the Champions League."
