A goal down at the break after a deflected effort left keeper Nicky Eyre stranded, the boys levelled seven minutes into the second period with a goal direct from a David Hicks corner. The winner was scored less than a minute later from a near post header following another corner.
"It is a disappointment after the last two seasons where we have done well - you are just hoping to get over the first hurdle and build up from there," reflected Pat afterwards. "It always makes the season more interesting and gives it some spice.
"I don't think we really got together as a team. We mentioned before that they must play as a team, keep their discipline, keep their movement and try and get round the back. It wasn't to be.
"We were a bit unfortunate with the goal that took a big deflection, the second one was disappointing because we'd just scored up the other end. You hope they will steady the boat a little bit and take confidence from that.
"From 1-1 and not playing well it is 2-1, we've got an uphill struggle and I had to change it a little bit hoping things will alter - but they didn't. In the end we just lost most of our discipline during the game and West Brom kept theirs.
"The boys are very low because, as we were saying to them before the game, this was their first real taste of what it is all about. They get to play at the main stadium with people looking, it is cup football and you've got to win."
Pat Holland conceded that his Youth Cup side did not really click as a team after the 2-1 reverse to West Brom in the 3rd round at the Hawthorns on Tuesday evening.
