Arsenal midfielder Francis Coquelin has claimed that teammate Theo Walcott is 'unstoppable' in his current form.

The speedy forward was a constant problem for Manchester United's defenders in the 3-0 win on Sunday and earned plaudits from his teammate for his performance.

"He has shown everyone he can play in this role up front," said French midfielder Coquelin.

"It was not only offensively, what he did defensively was amazing. He was defending, chasing the ball. It makes things easier for us at the back.

"When he is in this kind of mood he is not far off being unstoppable."
