Well, it has been a terrific day in the FA Cup so far, with Macclesfield’s history-making victory over Crystal Palace the undoubted highlight. There won’t quite be that kind of magic in north London this evening but rather an intriguing meeting of a couple of Premier League big beasts. Tottenham and Thomas Frank have been having a miserable time of it in the Premier League, where they have won just twice since October – a run stretching back 12 matches. Aston Villa, meanwhile, have been in sensational form, a return to the Champions League is basically nailed on and the only concern of note is keeping hold of Unai Emery. But in the FA Cup of late the form suggests a different story.
