Alan Irvine was full of praise for his Wednesday team after leading the club to the FA Cup fourth round for the first time in 10 years.
Second half goals from Gary Teale, Neil Mellor and Clinton Morrison secured a 3-0 win that put the skids under Championship side City and gave the League One underdogs a massive boost and Irvine was delighted with the performances of debutant defenders Michael Morrison and Reda Johnson.
Irvine said: "I've just been told that it's 10 years since we have got this far in the competition and that was a huge surprise to me.
"You would think a club of this size and with what it has achieved in the past would have done better, but it makes this result even more pleasing.
"I told the players at half time that they were better than they were showing. We gave the ball away too much and did not show enough self belief.
"The second half performance was tremendous. Goals change games and by the end everyone wanted the ball and every player was showing composure on it."
