In 1973 a 0-4 at Ajax Amsterdam in the European Cup, the 1977 UEFA Cup match at Eintracht Frankfurt, the 2009 Champions League trip to FC Barcelona under Jürgen Klinsmann, and the 2014 home semi-final against Real Madrid. More than a whiff of humiliation, though, attached to the 0-4 in the UEFA Cup semi-final at Zenit St Petersburg. Only once did the scoreline read 1-5: in the 1980 UEFA Cup semi-final at bogey team Eintracht Frankfurt, but only in extra time.
