Wolves managed to win 2-1 over Manchester United at the Molineux on Saturday.
Morgan said: “People should not be overly surprised because we have played some fantastic football this season. We’ve had horrendous luck but it all came together and the whole club is absolutely delighted.
“We’ve got to build on that from now on. It’s in our hands. If we show the same spirit that we showed (against United) we’ll be absolutely fine.”
