Shane Duffy has revealed how his defensive instincts saved Albion from an even more anxious second half in the FA Cup against Derby County.

The Irishman retreated to head clear a shot by Harry Wilson soon after half-time.

Derby had to wait until nine minutes from the finish to halve their arrears through Ashley Cole, brought on with Marriott by Frank Lampard at the interval.

Duffy told the Argus: "I dropped off because I knew I couldn't get to block the cross. I don't know if Butts (David Button) was behind me or not to save it. Anything to keep the ball out of the net.

"It would have been a lot more nervous but that's moments in matches. We could easily have finished it earlier second half.

"They had nothing to lose, went to 4-4-2 and just went for it, caught us a little bit by surprise. I think we dealt with it well enough.

"It was a sloppy goal (Cole's) but we had enough chances going forward. We're all happy.

"It's nice to get a win. We obviously made hard work of it in the end, but it's a good win and I think we deserved it with our overall play."
