Arsenal boss Mikel Arteta admits Pierre-Emerick Aubameyang's suspension is a big blow.

Aubameyang will be unavailable for the Gunners' next three matches after being sent off in the draw at Crystal Palace.

Saturday's opener was Aubameyang's 16th of the season and 14th in the Premier League - the rest of the squad have scored 15 league goals between them.

“We are losing probably the most important player," said Arteta.

“This is never nice but we have other players that can play in that position. We will try to find a way and be as competitive as possible.

“Hopefully [the other players] can take a step forward now that Auba is not able to contribute to the team with goals.

“Someone else has to do it and I want to see their reaction too."
