Each season the most successful clubs from each of the home nations qualify for the four Europe-wide club competitions organised by UEFA—the UEFA Champions League (formerly the European Cup), the UEFA Europa League (formerly the UEFA Cup) and, starting with the 2021–22 season, the UEFA Europa Conference League for men, as well as the UEFA Women's Champions League. England has produced winners of both the men's and women's Champions Leagues, and Scotland has produced a winner of the men's version. Linfield of Belfast's run to the 1966–67 European Cup quarter-final is the furthest any Northern Irish or Welsh team has reach in the premier European men's competition. Historically Welsh men's clubs were able to qualify for the now-defunct UEFA Cup Winners' Cup by winning the Welsh Cup: a number of Welsh teams enjoyed runs into the latter stages of the competition, with Cardiff City going furthest by reaching the semi-finals of the tournament in 1967–68.
