The winger set up the opener, an own goal by Gareth McAuley, and also forced a stunning save out of Ben Foster but felt a lot of credit needs to go to his colleagues at the other end of the pitch after the Baggies were shut out.
"It's always a concern when you're one-up and we were playing counter-attacking as they were having more possession," he explained to MUTV.
"As soon as Robin [van Persie] got the second goal, the game was over but we defended brilliantly. The back four and the keeper were fantastic today.
"Getting a clean sheet is brilliant. Every one of them at the back was fantastic and deserve a pat on the back and a clean sheet for how much work they put in. It wasn't an easy pitch out there today. It was boggy and everybody will be tired tomorrow because they put in a good shift.
"I don't think we wanted that drama again after the other night [against Newcastle]. We wanted to get off to a good start, which the manager said, and we managed to do that."
