West Bromwich Albion boss James Morrison told BBC Radio WM:
"We were a little bit sloppy at times but we regrouped and went again – that's the sign of a good team.
"Our penalty record in the last two years has been horrendous, so it was just good to see one go in.
"It felt like Burnley couldn't handle our intensity really, and I could smell that at half-time.
"My job is just to keep feet on the ground and to keep the lads working hard. It's just now a case of not getting carried away."
Burnley head coach Nicky Hayen:
"We didn't have the energy, desire and hunger of the home team. You also have to give credit to West Brom.
"You can always say we played a bad game but they had the structure, a lot of good energy, hunger and desire.
"We had problems and no solutions. I didn't expect this – it was an eye-opener for everyone, myself included.
"We didn't play as a team – more like individuals. We have to go back to basics like last week (the 2-2 comeback draw against West Ham). We played at slow motion."
