Southampton boss Ralph Hasenhuttl has praised Mikel Arteta's Arsenal side.
The Gunners looked to have gotten over their early season struggles, but have experienced a few indifferent results in recent matches to dent their progress.
As Arteta searches for a winning formula, particularly away from home, Hasenhuttl offered him words of encouragement.
The two teams go head to head in the Premier League at the weekend.
Hasenhuttl said: "After a difficult start they have had a good turnaround and stabilised the squad.
"Their last two defeats are against good sides, Everton and Man United.
"They have a very good side and have found their shape and their team I think it took a while but it seems they are settled.
"This is a tough challenge for us, at home they are strong.
"We need to have a good performance and have shown this against the top teams this season also so we can go there with self-confidence."
