Manchester United complete Karim Cassim signing (from Man City)

Manchester United have made Karim Cassim official: the 17-year-old midfielder has completed his move from Manchester City to Old Trafford, in a deal that Fabrizio Romano says is closed, as also outlined by The Athletic.

The transfer puts a young talent from City’s orbit into United’s plans. The club’s assessment of Cassim points to a specific profile in midfield: “an energetic box-to-box midfielder” who, according to The Athletic, can become a future first-team player.

A step forward at Old Trafford

This looks less like an immediate-impact acquisition and more like a long-term investment—bringing in a player with room to grow and the physical, high-tempo qualities United want to develop.

What happens next

With the paperwork completed, the key for Cassim now is adaptation: training with United’s setup and earning the progression that will determine how quickly he can move up the ranks.

For now, the headline is the official confirmation of the move and the clear message behind it: Manchester United believe in Cassim’s potential in the center of the pitch.
