"It's nice [to win] and I'm delighted to get another goal. It's my first of the season and hopefully the first of many. I felt good before the game, I've been training hard and just waiting for my chance.
West Brom came back strongly at the Hammers after the break and Victor Anichebe was only denied a late equaliser by a fine save from Adrian, but Nolan felt his team showed good resilience to repel the Baggies' threat.
"You expect their response," he explained. "They're struggling for points and we're 2-1 up away from home. The Gaffer's decided to go with five at the back, soak up the pressure and see if we can hit them on the break with Enner's pace.
"I thought we did pretty well. It was fantastic to make sure they didn't score and we had to rely on Adrian on a couple of occasions, but all in all I thought the lads were brilliant. We've had a fantastic start, and [it's great] to get another win after three points on Saturday. We didn't play too well against Newcastle, but still getting the win shows you're a good side."
Looking ahead to Sunday and the prospect of recording a third straight Barclays Premier League win, Nolan says he hopes to add to his goal tally as soon as possible, especially as he is now just one away from the milestone of 100 league goals.
He added: "I've got a goal and I'm looking forward to another game against Swansea. I've got quite a good record against them from last season and I'm feeling good so hopefully I'll get my chance and score another couple."
