Around 42 ....
I should mention that in the FAPL they change jerseys every other season, so I have 7 Alan Shearer jerseys, 4 home team and 3 away team ones (they the home and away team ones interchangably each year, so next year I'm getting myself a new away team jersey). Other jerseys of players that don't even play there or at all any more, eg Jon Dahl Tomasson and Frank Pingel (both danes and autographed).
EDIT: and btw John, since you have already gone half the mile you should take the full step and get the FAPL sleeve marks as well (an extra £1.99).
