No . . . it's not a quiz - I genuinely don't know the answer.
But I pose the question the morning after Man Utd and Chelsea have both reached the semi finals - and Liverpool look like making it an English hat-trick.
Apart from Darren Fletcher, I can't think of any other Scots involved. It's changed days from whenat least one Scot was involved with Liverpool, Man Utd, Aston Villa or even Notts Forest at this level - either as player or manager.
So what IS the answser?
Was it Paul Lambert in his German years??
Or Fergie lifting it in 1999?
Somebody out there will no doubt keep me right . . .
