Stuart Slater was a poor buy, not because the lad wasn't a decent player (in very small flashes), but just because he didn't fit in with anything we needed at that particular time, especially for the money we spent on him.
The huns were filled with hammer-throwers and Celtic needed a bit more steel and dig. Wee Slater had all the physical presence of a paperweight and it just didn't work out for the player or club.
Celtic have signed worse players, so I guess it defeats the purpose of the thread, but it highlights how we were throwing money at all the wrong things at that time.
I'm not going to mention Carl Muggleton or Wayne Biggins (ooops, too late), it wasn't their fault that they got asked to sign for a footballing giant, but there were some strange signings through the Brady/Macari era that just didn't make any sense.
