Erik ten Hag's men had to make do with a point in our first league game of 2024, despite twice taking the lead.
Rasmus Hojlund got us off to a flyer with a thumping effort after three minutes and, following Richarlison's headed equaliser, Marcus Rashford made it 2-1 with a composed finish as he took advantage of a neat one-two with the Dane.
But Rodrigo Bentancur smashed home just 50 seconds into the second half and, despite further chances for both sides, it ended level - only our second league draw of the season.
Bar the goals, the loudest moment of the afternoon came when Martinez replaced Jonny Evans on 63 minutes.
