Unai Emery names three key Manchester United players and explains Aston Villa's plan to win

Last weekend's 5-0 win over relegation-threatened Sheffield United was only Villa's second win in the Premier League since Christmas and Emery's side we dumped out of the FA Cup in their fourth round replay against Chelsea midweek.
