Arsenal's Arsene Wenger and Manchester United's Louis van Gaal are both up for Premier League's Manager of the Month award after leading their teams to 100% records in March.
The Gunners negotiated Champions League disappointment to win all four of their games and move to within a point of second-placed Manchester City in the table.
Meanwhile, a much-improved United collected nine points from a possible nine, beating Tottenham Hotspur and Liverpool along the way, to consolidate their top-four place.

Ronald Koeman completes the quartet of nominees, having guided Southampton through an unbeaten March in which they drew at leaders Chelsea and recorded clean sheets in victories over Crystal Palace and Burnley.
