Chris Wilder was delighted to leave The Hawthorns with all three points, as Kieran Dowell's first goal for United proved decisive against promotion rivals West Brom.
Speaking in the aftermath of the success, Wilder praised his players for seeing the game out, but thought they should have won by a more comfortable margin.
He remarked: "We will only know the significance of that victory at the end of the season, but it was a game we were really up for.
"But you don't get the results we've had this season without being committed, if I'm totally honest I don't think it was our greatest performance, we gave the ball away far too cheaply at times and they could have hurt us.
"But from a positive point of view, the commitment, character and just the general togetherness was most pleasing."
Wilder added: "We lost Egan at half-time, Cranie's calf tightened up and Marvin Johnson hasn't played a lot of football, so we're delighted to have won a tight game against a talented group of players.
"We've still got to learn lessons though. We could have taken it away from the opposition and West Brom, in our position, would have probably won by three or four.
"But if we are to be playing top end Championship games towards the end of the season then hopefully it can be a lesson learnt."
