Arsenal attacker Leandro Trossard admits the players are frustrated over their sudden title collapse.
Arsenal have surrendered an eight point to Manchester City over the past month.
Trossard said: "We knew [City] would come close and it's all about us I think. Obviously, it's not in our hands anymore but before it was just looking at ourselves.
"If we would have won all those games, it would be a different story of course. But we gave them that a little bit to come back into the race and obviously now they are ahead of us.
"When you are competing on the highest level they're a top side as well, they show it every year.
"But I think it's down to us to be at this level as well to make it really hard for them as well I think. Like I said, we'll see."
