Tony Mowbray praised his players after their 2-0 FA Cup third-round replay over League Two Peterborough United which set up an interesting fourth-round tie against Championship outfit, Burnley.
Jay Simpson's first goal in Albion colours and Paul Robinson's opening goal of the season was enough to see off Darren Ferguson's men on a night when the Baggies controlled large spells on the tie.
In front of an expected London Road crowd hoping to witness a famous upset, Mowbray made four changes to his starting line-up with Ryan Donk, Kim Do-Heon, Filipe Teixeria and Roman Bednar all recalled.
"I'm delighted to be in the next round," the Baggies boss admitted.
"This was a potential banana skin but we did a professional job tonight.
"We're very respectful of Peterborough and the job that Darren Ferguson is doing here.
"We saw how good they can be at The Hawthorns - but I don't think they reached those heights tonight.
Mowbray continued: "I think the game at The Hawthorns had a strange atmosphere.
"It was nowhere near the intensity of a Premier League game and I think that played into their hands a little bit.
"It allowed them to raise their game and we were off the pace a little bit.
"I think we felt that was probably their best chance of getting through the tie.
"We knew there would be an intense atmosphere in the stadium tonight and that would suit us better than the first game at The Hawthorns.
"We came here twice last year and won in both cups so tonight held no fears for us.
"Leon Barnett and Ryan Donk did exceptionally well at centre-half.
"They're strong, athletic, powerful boys who had he qualities to see off Peterborough's goal threat."
