The Portuguese coach appears to have a very clear idea as to how he expects his wingers to behave on the pitch and for all intents and purposes, both the Englishman and the Argentinian seemingly weren't up to the lofty standards that Amorim expects.
No future for Garnacho at Man United
It certainly didn't help Garnacho when he took aim at his manager in the press, and the 20-year-old surely would've understood what the implications of his outburst would be.
Amorim's response - telling the player to find a new club in front of his United teammates - has been well documented, though a £70m asking price could put off potential purchasers.
Over the past three seasons, since breaking into the United first-team, Garnacho has scored 23 goals and provided 15 assists in 115 games, 73 of which he started.
A goals-to-games average of around one in five isn't the worst return, but it could certainly be improved upon.
One area where the player hasn't been given too much credit is with regards to his passing accuracy. As high as 90.8% over the past couple of years has gone under the radar, as has a respectable 116 chances created in the same time frame.
It might also surprise many to understand that the Argentinian has also won back possession on 309 separate occasions and made 47 interceptions, suggesting that he has more than earned his place in the United starting XI.
Perhaps Amorim's forceful stance could come back to haunt him were, as will be expected, Garnacho signs on somewhere else in the current transfer window.
Plenty of interest in Garnacho
Although it was believed that both Napoli and Bayer Leverkusen were interested in the player, there's a belief that he would prefer to stay in the Premier League which has alerted the likes of Aston Villa, Tottenham Hotspur and Chelsea, the latter of whom have just sent another United winger, Jadon Sancho, back to Old Trafford.
Villa also enjoyed Rashford's services in the second half of last season, so it's completely understandable why they too would be looking to secure a player who thrives on beating his opposite number and can play equally well on the left or right side.
Given that Spurs already have Wilson Odobert and Brennan Johnson as their right wingers, the notion that Garnacho could be the long-term replacement for Son Heung-min gains credence.
There is much speculation surrounding the 32-year-old's next move and whether he decides to leave the club this summer or next but either way, it's clear that Son's time in north London is coming to an end.
New manager, Thomas Frank, ideally needs to make a splash in the transfer market, and landing Garnacho would certainly have the rest of the Premier League sitting up and taking notice.
That Tottenham have qualified for next season's Champions League will almost certainly be a factor in negotiations too.
Could the Argentinian replace former teammate Rashford at Villa?
Taking the view that Leon Bailey and Donyell Malen have the right-sided spot locked up at Villa, the United wide man could be a like-for-like replacement for his former United colleague, Rashford.
Looking at the 27-year-old's stats from the second half of the 2024/25 campaign, four goals and three assists in 13 games in all competitions is a decent one-in-three return, and he certainly proved a point to Amorim - and maybe himself - during that brief period.
An 88.3% pass completion was on par with Garnacho for the same time frame, whilst winning 70% of his tackles showed a determination that had all but left him at United.
Were it not for Villa's inability to qualify for the Champions League, there's little doubt that Rashford would still be working under Unai Emery, albeit on a more permanent basis, and the Midlands-based outfit wouldn't even be considering the Argentinian.
Chelsea going after Garnacho makes no sense
Chelsea are seemingly always busy in transfer windows these days, and this summer is unlikely to prove any different.
The Blues have spent €803m on strikers and wingers alone since 2020, and with the likes of Pedro Neto and Noni Madueke already in situ, and Estevao Willian shortly to arrive, it begs the question as to why the club, who have appeared to lack any sort of cohesive direction in the transfer market of late, would also want to go after Garnacho.
Madueke's eight goals and three assists in 36 games last season is, again, not too bad, but for a team chasing silverware and titles, he's not at the level required.
What he lacked in attacking terms, Madueke more than made up for with his defensive responsibilities, however, winning 21 of the 27 tackles he attempted. His 92.9% pass completion in 24/25 is also worth noting.
A move for Garnacho, therefore, doesn't make an awful lot of sense, and unless the Old Trafford hierarchy are prepared to move on their valuation, it may well be that United are stuck with a player that their manager doesn't want and who doesn't want to be there either.
