Feyenoord defender Tyrell Malacia's move to Manchester United have been delayed due to agent issues.

Feyenoord have accepted a bid rising to €17m from United for the left-back this week.

However, the move has been delayed as agent Ali Dursun currently lacks the necessary papers to negotiate on Malacia's behalf with United, says the Athletic.

Instead, Malacia's father will step in to finalise terms for his son.

Dursun and United are facing a similar issue involving Barcelona midfielder Frenkie de Jong, who is also his client.
