Swansea City scored the day's biggest upset when they knocked holders Portsmouth out of the FA Cup with a deserved 2-0 fourth-round win at Fratton Park on Saturday.
Portsmouth, who beat Cardiff City in the Cup final in May, had no answers against another Welsh side, Championship (second division) Swansea winning with goals from Nathan Dyer, on loan from Portsmouth's arch-rivals Southampton, and a penalty from Jason Scotland.
There was little room for FA Cup romance elsewhere with none of the other unfancied teams managing upset victories.
