Ralph Hasenhuttl has praised Crystal Palace manager Patrick Vieira, but believes Southampton can exploit their defensive frailties.
The two sides will meet at St. Mary's on Wednesday, with Palace riding high after a 3-1 win over Everton on Sunday.
Asked about Palace's attacking style, Hasenhuttl said: "This can be also an advantage as sometimes you get more space for the counterattack, but you have to say also that their reverse gear is becoming also better.
"It was definitely a very good performance that they shown yesterday, we have to go there and not be surprised if it is a tough game to play."
And when quizzed about how Vieira has performed so far, the Austrian added: "After a tough start where they had a few issues, they were finding each other very quickly.
"It's always tough for a new manager with pre-season to bring your way of playing football in the Premier League.
"But it looks more and more that the quality in every position is very flexible with every gameplan, this gives a very competitive team and is the reason why they have had some good results.
"They have also dropped a few points from winning positions which is sometimes our problem, but in total it's an opponent who is strong."
