Success for them relative to Scotland would be getting out of their group, which they often do when they qualify for the World Cup. For example in 1966, 1970, 1974, 1986, 1990, 2010, 2014 and 2018
Actually surprised by that mate - never knew Scotland never got out their group TBF, prob would have lost money on that - could have sworn the England game in Euro 96 was later round game but prob wrong.
Fair play, but Uruguay and Croatia are still outliers to the mean - frequency dictates there will always be one or two - even we got to the Quarter Final and beat eventual finalists Italy in WC.
