I saw Ruben Amorim's angry reaction - it taught us something about the Manchester United head coach

Manchester United won 4-0 against Everton in the Premier League on Sunday afternoon.

Ruben Amorim claimed the first win of his tenure against Bodo/Glimt in the Europa League earlier in the week with Alejandro Garnacho and Rasmus Hojlund on the scoresheet.

United had a two-goal advantage by half-time against Everton after goals from Joshua Zirkzee and Marcus Rashford and the latter made it 3-0 just 25 seconds into the second half.

Zirkzee scored again after some brilliant, aggressive pressing from Amad shortly after the hour mark and the win moved United into the top half of the Premier League table. Amorim now has momentum behind him ahead of an important game against Arsenal at the Emirates.

Here are the moments you might have missed from the game:

Amorim is a ruthless coach

United started well against Everton, looking bright and creating chances, but the away side grew in confidence and Amorim cut an increasingly frustrated figure.

The 39-year-old is animated on the touchline and he reached boiling point after just 25 minutes when he turned to the bench and ordered Garnacho and Mason Mount to warm up. United had just lost the ball and Amorim swiftly reacted by preparing two replacements from the bench.

United's bench was worth in excess of £330million on Sunday afternoon and there were options aplenty to choose from, which meant anyone underperforming could be hooked.

Thankfully, United fashioned a two-goal advantage before the interval, which meant no half-time changes were required, but Amorim showed his ruthless side by preparing substitutes.

Appreciation for Mainoo

Kobbie Mainoo made his first start under Amorim against Everton and performed well. The youngster started alongside Casemiro and made a pleasing return to action after his muscle injury.

Although it seemed a tad strange that Mainoo hadn't been given a single minute in Amorim's first two games, it was too early to panic and he finally started against the Toffees.

Mainoo is supremely talented when he's fit, and he received great applause from each corner of Old Trafford when he was replaced by Mason Mount with 10 minutes remaining.

Amorim described Mainoo as "one of the best youngsters in the league" before facing Everton and the academy graduate should take his game to another level working with him.

Dalot coming and going

Amorim crouched down and slapped his knees when United had trouble trying to build from the back at one stage. Just a few minutes later, he was barking orders at Diogo Dalot and the defender did the opposite of what he wanted, moving backwards instead of pressing the ball.

Dalot started at left wing-back and started well, playing in a brilliant cross, but he didn't know whether he was coming or going at times when Everton were attacking down his side.

There were always going to be teething problems with Amorim's new system and understanding what the new head coach wants in the wing-back positions is a challenge for Dalot.

Dalot suffered a slow start to the season - he has failed to reproduce the same standard of performances as last term - and needs patience as he adapts to his new role.

United's set-piece coach

Andreas Georgson was appointed as United's set-piece coach in the summer and was retained as part of Amorim's backroom staff, despite the bulk of Erik ten Hag's coaches departing.

Georgson was a Jason Wilcox appointment and has a strong CV, but he no longer stands on the touchline for set-pieces, so what is his current role?

Carlos Fernandes, who is Amorim's right-hand man, comes out to observe set-pieces and Georgson doesn't even come out to stand alongside the 29-year-old. It would be interesting to hear how Georgson's role has changed after Amorim's arrival because it's currently not clear.

The ticket protest

United have made the mid-season decision to raise matchday ticket prices to £66 per game, with no concessions for children or pensioners, and fans gathered around the Trinity Statue before facing Everton to protest the hike, which has been described as a "kick in the teeth".

Fan group The 1958 were responsible for organising the protest and Everton fans peacefully joined forces to speak out against rising ticket prices. Manchester City and Liverpool fans also came together before their game at Anfield and it's important the message is heard.

Sir Jim Ratcliffe has done a lot of good since becoming United co-owner, but his mistakes are beginning to add up and he should make a U-turn on the price hike after fans expressed their anger.

There were expletives aimed at Ratcliffe during the protest and he was as much a target as the Glazers, which suggests his honeymoon period in Manchester is over.
