Unai Emery and Arsenal missed a rare opportunity to extend the gap on top four, as the Gunners came crashing at the Emirates against Crystal Palace.
Goals from Christian Benteke, Wilfried Zaha and James McArthur were just enough to stop Arsenal, as Mesut Ozil and Pierre-Emerick Aubameyang could only help the hosts to two goals of their own.
Arsenal remain fourth despite the loss to Palace, but are only ahead of the West London blues on goal difference, with Manchester United not far behind by two points.
Speaking to BBC after the game, Unai Emery admitted to have been bested on set pieces, but also admitted they were their only obstacle to a top four finish.
“In the first half with the possession we were better. The second half we started well and we drove.”
“The second goal gave them confidence to continue and beat us. Our second goal gave us opportunity.
“They were very good tactically and were organised defensively. In the set pieces they gave us a problem.
“We brought on Alex Iwobi and we were better but their second goal was very bad for us and took away our confidence.
“We had fresh players and energy but in front we had a very good team. To finish in the top four is in our hands.”
