Association team allocation
A total of 64 teams from 31 UEFA member associations participate in the 1978–79 UEFA Cup. The original allocation scheme was as follows:
3 associations have four teams qualify.
3 associations have three teams qualify.
18 associations have two teams qualify.
7 associations have one team qualify.
East Germany and Bulgaria were the two associations selected to have a third birth for this season, while Poland and Switzerland went back to two qualified teams.
Wales: There was no national league in Wales before 1992 and the only competition organised by the Football Association of Wales was the Welsh Cup so Wales had just a single participant in European competitions, the winner (or best placed Welsh team as several English teams also competed) of the Welsh Cup which competed in the UEFA Cup Winners' Cup.
Albania: Albanian teams returned to European competition in 1978 after five years of absence, but the country choose to not participate in the UEFA Cup, which wouldn't happen until 1981. Luftëtari would have qualified for the UEFA Cup by league position.
