Liverpool - Manchester United manager Louis van Gaal has managed some of the world's top clubs and his country's national team on the biggest occasions but he still ranked Sunday's 2-1 victory over Liverpool as one of the most important moments of his career.
With the race for a top-four finish in the Premier League becoming increasingly tense, United struck a potentially decisive blow with goals from Juan Mata in each half helping them move five points clear of Liverpool in fourth place.
United were the better side for most of encounter and Van Gaal said the victory was forged from playing Liverpool at their own game.
