West Brom boss Tony Pulis was delighted with victory over Arsenal.

Craig Dawson scored twice for the 3-1 win.

Pulis admitted that he had worked on set-pieces this week and felt Arsenal were vulnerable.

"They mark zonally so you have to do it a bit different," said Pulis.

"We spent a bit of time on that, we knew if we got the right quality in with the right movement we would get chances.

"Managers do it differently. There are some top managers and great teams who mark zonally. It's just preparing.

"The ball has to be the quality that it was today and then you need to get in those spaces. Luckily for Dawse (Dawson) he got in those two spaces and got two goals."
