The Baggies have earned a reputation as a cagey team, difficult to beat, who like to draw teams in and hit them on the break.
On Sunday, despite falling behind to an early goal, it was the visitors making most of the running and they put on a good show in front of a live television audience.
Even though the team were not at their best, John reflects that it was still three points won - even though he was not happy with the performance.
"We knew it would be a difficult game but, to be fair to West Brom, they did something that was unexpected," he said.
"I spoke to their manager and coaching staff afterwards and they changed their tactics. Instead of being tight, sitting back and hoping to hit us on the break, they had a go - and give them credit, they did do.
"I did the same with Swindon Town and I don't know whether it will work for them because it is difficult. We've got the quality as you saw on Sunday - when we had the chances we took them. In fact, we could maybe have got two or three more goals.
"Saying that, they could have as well because of their attitude and we were lucky at times.
"At the end of the day we've got the three points, but we were disappointed again because we want to play better. Credit to them though for the performance they put on against us.
"Let's be honest, apart from the Middlesbrough game, that was our worst home performance - but we still won the match. I'd rather win the match 3-1 and not play well than lose the game 3-0 and play the same.
"We got a good result, but we know we've got to play better against Arsenal next week."
John Gorman says the tactics employed by West Brom on Sunday came as something of surprise to the management team.
