... or the "didn't quite make it" slide, as it is sometimes known.
In the first of three goalkeepers not to make the list, but still deserving of a mention, Theo Snelders of Aberdeen (1988-96) and Rangers (1996-99) fails to get in because his best years were with the Dons and thus not in the SPL years.
Andrius Skerla stuck with Dunfermline even after Rangers were linked with him during his first year with the Pars. Signed from PSV Eindhoven for around £200,000, the Lithuanian defender stayed for five seasons before departing for Russian side Tom Tomsk in 2005.
Argentine icon Claudio Caniggia turned out for two Scottish clubs—Dundee (2000-01) and Rangers (2001-03)—and impressed greatly. The forward with the rock star look captured the imagination, especially at Dens Park, and will be fondly remembered by fans of both clubs he played for.
Sticking with Rangers, goalkeeper Stefan Klos arrived at the club a European Cup winner with Borussia Dortmund. During an eight year stint (1999-2007) in Glasgow, the German established himself as a formidable presence between the sticks, won every domestic club honour available, captained the side and made almost 300 appearances.
Another ex-Rangers 'keeper deserves a mention, though not for his performances with the Ibrox side. Finnish stopper Antti Niemi played in Scotland between 1997 and 2002, spending the first two years with Rangers and the next three with Hearts. It was with the Jambos he shone, gaining many plaudits and subsequently moving to England where he spent six seasons with Southampton and Fulham. He was even touted for a call-up to the Scotland team by one indignant Hearts fan!
Jorg Albertz, or "the Hammer" as he was nicknamed, possessed probably the fiercest shot ever to rattle the back of an SPL net. He managed that 76 times in 211 games over the course of his five years at Rangers (1996-2001) and played a role in winning three league titles, two Scottish Cups and two League Cups.
Australian forward Mark Viduka took no such time to settle in at Parkhead when he arrived from Croatia Zagreb in 1998. He left pretty sharpish—playing the equivalent of one full season in his year-and-a-half in Glasgow—but left with the League Cup and Players' Player of the Year award in 2000. A return of 35 goals in just 48 games is why he deserves a mention.
Finally, staying Down Under, ex-Motherwell and Celtic striker Scott McDonald was a clinical finisher during his years in Scotland. The Australian netted an impressive 93 goals, placing him fourth of all time in the SPL history books.
