Southampton manager Ralph Hasenhuttl admits he is concerned about facing Arsenal.

The Saints are hoping to inflict more misery on the North London club.

But after two defeats since the restart, Hasenhuttl admits the Gunners are a wounded animal that may strike back against Southampton on Thursday.

"He (Mikel Arteta) has a strong team - it's never or a good moment [to play them]," Hasenhuttl said.

"It's always difficult because they have quality, they have fantastic players and it's always to play the game.

"Even if they have a few injuries, the quality is so big they can absolutely hit back immediately and if you give them a little space, they are unstoppable with their speed.

"We must really take care, really pay attention of everything and finally make it a very good game."
