As the longest serving current player of Manchester United, Shaw was extremely frustrated because he was omitted outside the six -member leadership group of Amorim.
Club skipper Bruno Fernandes leads a small set of lieutenants, including Harry Maguire, Noussair Mazraoui, Lisandro Martinez, Diogo Dalot and even backup keeper Tom Heaton.
And Shaw was rumbling about being hunted, with Amorim hoping that the disappointment of the 30-year-old at the start of the new season is rubbing.
It apparently seemed to have influenced Shaw's performance in the training, whereby the left back did not seem to push itself 100 percent.
To make matters worse, the 19-year-old center-back Leny Yoro was extremely close to making the sextet of leaders.
But Amorim decided to keep Yoro out now, although the boss thinks that the French teenager will be the pillar of the back line and become a club legend.
Shaw is the most experienced player at Carrington and has in fact been for the entire Post-Sir Alex Ferguson era.
He has left for two years at his deal of 180,000 a week and was once considered one of the best full-backs in the Premier League, but he shows weakness in defense and positioning.
Money -saving
The days that Alexis Sanchez earns £ 500,000 a week in Manchester United have long since disappeared.
The Red Devils will sign Benjamin Sesko their fourth summer in a £ 74 million step from RB Leipzig.
But United seems to have adopted a new strategy in terms of wages, where none of the new recruits pick up more than £ 200,000 a week.
Matheus Cunha would be £ 180,000 a week after his £ 62.5 million from Wolves.
While ex-Brentford-star striker Bryan Mbeumo is also supposed to have a salary of £ 150,000 a week after registering for £ 71 million last month.
Leon, 18, is seen as a development player, so it would not recommend wages near the top earners in the club such as Casemiro and Captain Bruno Fernandes.
Sesko's wage package seems to be in the same modest braces as Cunha and Mbeumo as United try to continue their rebuilding under Ruben Amorim with contracts that are more focused on performance.
In 2018, Sanchez arrived in Old Trafford from Arsenal and played the piano when he ordered a mega financial package, but the Chilean was not in accordance with a miserable spell of 18 months.
Paul Pogba, Cristiano Ronaldo, David de Gea and Marcus Rashford have been high earners in more recent seasons, but this period will not be in Amorim's first team.
Perhaps United has finally learned from their mistakes from the past, since the club strives to maintain a culture shift.
Nuno Mendes 2.0
Ruben Amorim believes that Patrick Dorgu has the potential to become the next Nuno Mendes 2.0.
Insiders have told Sunsport that the Portuguese Gaffer Dorgu 'loves' after he has helped him improve his profession during their first full advance season.
The left wingback, which went through a difficult start of life at Old Trafford, but showed moments of promise in the midst of the unrest, was one of the largest take -away restaurants in the American tour.
Dorgu, 20, played a key role in attacking the flanks in all three games of United's Victorious Premier League series, while he scored and assisted against Bournemouth.
Comparing the DANE with the best left back in the world in PSG's Mendes is perhaps a bit a bit, but it shows how much Amorim assesses him.
Although he did £ 30 million from Lecce in January, Dorgu will become an important player this season, which means that Luke Shaw will find it difficult to earn his place back.
Shaw, who came to United in 2014, will play for an opportunity to come to the English team of Thomas Tuchel for the World Cup 2026.
Red Goodbye
David de Gea is not the only 'legend' who has a presentation in Old Trafford on Saturday.
In the press room, the long-term Sunsport reporter Neil Custis will also receive a shipment of the Red Devils after he has brought the curtain over the club at the age of 26.
Clear movement
United fans are desperately looking for more new faces this summer -especially Brighton -midfielder Carlos Baleba.
Ruben Amorim is a big fan of the Cameroonian, but it is unlikely that the £ 100 million + needed to buy it during the current transfer window.
So a united dedicated – known as 'Ian M' has started a crowdfunding page to help Jim Ratcliffe raise the required money.
On Friday afternoon the figure was £ 254 … a way to go Ian.
Young devils
European clubs are already sniffing around the next talented teenager from the Carrington production line.
Scouts from Central Europe have made notes about the under-19 team of Manchester United during a tournament in Croatia, and one Red Deviljonger has already turned its heads.
United has sent a young team to the Mladen Ramljak tournament with 15-year-old Kai Rooney and JJ Gabriel, still only 14, playing next to and against many older children.
But the excellent player in their opening match – a 1-0 win over Rapid Vienna – was midfielder Amir Ibragimov, who converted Cooly the punishment that decided it.
The 17-year-old has long been advertised as an old First Team of Trafford of the future and the word of his potential has traveled far.
A explorer who watched the game from the stands told a Croatian reporter that Ibragimov was the one who watched.
“He is by far the most serious player in the tournament,” the limited official told 24Sata.
That is serious praise, given Benfica, who operates the most profitable youth academy in the world, Juventus and the local population also participate in the tournament Dinamo Zagreb.
The tireless Ibragimov ordered the midfield against Rapid and was a vocal presence during the competition while constantly organized and organized his teammates from the middle of the field.
The teenager born in Dagestan is one of the four brothers with two of his younger brothers and sisters also at United's Academy.
The oldest brother is Ibragim “The Mauler” Ibragimov -an unbeaten MMA hunter with four wins in a row in the PFL -Cage.
Bombarded
The 'Bomb Squad' has not been forgotten in the £ 50 million makeover of Carrington.
Alejandro Garnacho, Antony, Tyrell Malacia and Jadon Sancho all have a pen and cupboard in the new dressing room of the first team.
Every place also has a touchscreen -path to let them know their schedules for the coming days.
It is interesting, however, that, unlike the other three, former England -wing player Sancho, no number has been assigned.
The quartet all trains away from the first team team while they want to protect from Old Trafford for the next three weeks.
