Under the management of Matt Gillies and his assistant Bert Johnson, Leicester reached the FA Cup final on another two occasions, but lost in both 1961 and 1963. As they lost to double winners Tottenham Hotspur in 1961, they were England's representatives in the 1961–62 European Cup Winners' Cup. In the 1962–63 season, the club led the First Division during the winter, thanks to a sensational run of form on icy and frozen pitches the club became nicknamed the ""Ice Kings"" eventually placed fourth, the club's best post-war finish. Gillies guided Leicester to their first piece of silverware in 1964, when Leicester beat Stoke City 4–3 on aggregate to win the League Cup for the first time. Leicester also reached the League Cup final the following year, but lost 3–2 on aggregate to Chelsea. Gillies and Johnson received praise for their version of the "whirl" and the "switch" system, a system that had previously been used by the Austrian and Hungarian national teams. After a bad start to the season, Matt Gillies resigned in November 1968. His successor, Frank O'Farrell was unable to prevent relegation, but the club reached the FA Cup final in 1969, losing to Manchester City 1–0.
