If you look at Ireland's Italia 90 squad, then it appears jack Charlton only took two keepers to the tournament.
However, Ireland did have a third keeper registered - Niall Quinn.

Perhaps, in an attempt to show similar versatility to Martin O'Neill, Shane Duffy may have had this in mind while playing for Blackburn against Preston yesterday.
24 minutes into the game, Duffy prevented a goal-bound shot from hitting the back of the net when he slid across the line and got a hand to the ball.
Moments later, Duffy was shown a red card and Preston awarded a penalty.
Blackburn were 1-0 up at the time and would go on to lose 2-1.
