Don't look back: Alnwick lies stranded as Chris McCann scores for Burnley
Alnwick was at fault for two goals as his side threw away a 4-1 first-leg, semi-final lead. Thankfully for the former Sunderland man, Roman Pavlyuchenko and Jermain Defoe struck late in extra-time to save his blushes.
But he is not alone. Here is Sportsmail's guide to six of the worst debuts.
DEBUT DUNCESGlenn Keeley (Everton)
The defender, on loan from Blackburn, made his debut in a Merseyside derby in 1982. Half an hour later, he was sent off for fouling Kenny Dalglish as the Liverpool striker was through on goal, and Everton went on to lose 5-0.
Real hope: Woodgate's arrival in Madrid
Jonathan Woodgate (Real Madrid)
He waited more than a year to make his bow in Spain after leaving Newcastle, but when it came it was certainly one to forget. The England centre half first scored an own goal to gift Athletic Bilbao an opener, and then was sent off as Real crashed 3-1. An inauspicious start.
Billy O'Rourke (Burnley)
The young goalkeeper was given his chance for against QPR when No 1 Alan Stevenson was injured. To say it did not go well is an understatement as O'Rourke conceded seven goals, which were shown in all their glory on Match of the Day later that night.

Welcome to England: Sinclair gives Evra the run around on the Frenchman's United debut
Patrice Evra (Manchester United)
Now he's probably the best left back in the Premier League, but Evra's debut was a horror show. He was given the runaround by Trevor Sinclair in a Manchester derby, and was taken off at half-time as City beat United 3-1.
Roy Keane (Celtic)
One of the Premier League's finest ever players, but made less of an impact on his first game north of the border. A Scottish Cup game against Clyde should have presented little difficulty, but the minnows won 2-0 to leave Keane and Co humbled.

Curtis Davies (Aston Villa)
A highly-rated defender he may have been (and still is), but Davies admits to playing 'like a pub player' on his Villa debut, a 1-0 Carling Cup defeat by Leicester. Has, thankfully for Villa, improved dramatically since that night.
