The Portuguese coach was scheduled to officially begin his tenure at Old Trafford on Monday, with his first match in charge against Ipswich Town on 24 November following the international break.
Amorim’s final game in charge at Sporting Lisbon is against another of his former clubs in Braga on Sunday night. The 39-year-old is scheduled travel to the UK Monday morning.
But the Daily Telegraph report his start will now be delayed until later in the week with paperwork on his visa still to be finalised.
While he is still set to arrive in the UK tomorrow, Amorim will not be able to officially begin work at the club’s Carrington training base until those final details are rubber-stamped.
That minor delay is unlikely to have a major effect on Amorim’s immediate plans with most of United’s first-team squad away on international duty.
England trio Marcus Rashford, Harry Maguire and Kobbie Mainoo are among those still at Carrington, with the forward not selected in the latest Three Lions squad and the latter two recovering from injury.
Amorim is expected to have his full squad back in Manchester and ready to work on Thursday week before his first game in charge against Ipswich.
Ruud van Nistelrooy has been in charge of United’s last four games having stepped in to take charge as interim boss following the sacking of Erik ten Hag.
The former United striker returned to the club to join ten Hag’s backroom staff in the summer and has a contract until 2026. While van Nistelrooy is eager to stay on and work with Amorim, his future is uncertain with the Portuguese expected to arrive with his own trusted team in tow.
‘We will learn what the further plan is now,’ van Nistelrooy said after his final game in charge, a 3-0 win over Leicester City.
‘I am here to support the club and I want to continue that. I was told after this block of four matches, there will be communication towards you and your colleagues [about the future], so I expect to hear today [Sunday] or tomorrow [Monday].’
