There have been no rumours at all linking Martial with a move to Old Trafford and the move comes as a surprise.
Aged just 19-years-old, the player has been generating buzz in France following some energetic displays.
Offering €50m for someone so young seems like a stretch but Manchester City did pay £49m for Raheem Sterling earlier in the window.
Unfortunately, clubs are aware of United’s situation and they were always going to pay a premium for players this late in the window as a result.
Nevertheless, it will be good to get someone in rather than no-one at all. Sometimes the excitement surrounding a late signing can spur a team on for the season ahead. Martial is largely an unknown quantity but United must have done their homework if they are willing to pay so much.
