Aston Villa may not get the Christmas they may have hoped for this year, as they face Manchester United in the best form they have been in since Sir Alex Ferguson retired.
Louis van Gaal has finally managed to get United performing, however he is still adamant he wants more from his men - and if he gets what he wants on Saturday, it could be a bad day to be a Villa fan.
The Red Devils have won six Premier League matches in a row and welcome back both Radamel Falcao and the Argentine Player of the Year, Angel di Maria.
To add to the misery, Paul Lambert faces a difficult decision when it comes to team selection, with Tom Cleverley (who could not play against his parent club anyway), Kieran Richardson and Alan Hutton all suspended.
The Villa are without some key players due to injury too, as Ashley Westwood, Joe Cole, Philippe Senderos and Nathan Baker are all unavailable.
On a plus side, both Ron Vlaar and Fabian Delph are available for selection.
We look at three key battles which are sure to have a big impact on the game this Saturday.
