Manchester United's efforts to secure Rúben Amorim as their new manager are currently facing delays due to a 30-day notice period required by Sporting Lisbon. The club is eager to have Amorim in charge ahead of Chelsea's visit this Sunday, but this timeline may be challenging to meet without a resolution in ongoing negotiations with the Portuguese side. United has expressed their intention to activate Amorim's €10 million (£8.3 million) release clause, but the situation remains complicated as they seek a solution that would allow for a quicker transition. The club is actively working with Sporting to find a way forward.
