A sublime Casemiro double formed part of a large Brazilian influence that helped steer Manchester United into the fifth round of the FA Cup as they beat Reading 3-1 at Old Trafford
Erik ten Hag's side were dominant throughout as their recent spell of good form continued, although they were unable to find a way past a committed Royals defence - the visitors managed by former United midfielder Paul Ince - in the first half
As it turned out, the game needed a sprinkle of Brazilian magic as Casemiro, Antony and Fred helped guide Man Utd through
 They also recorded an 11th successive home win in all competitions
Midfielder Casemiro scored twice shortly after the break
 Antony picked out his team-mate with a world-class pass for the opener (54) before a Fred assist saw the former Real Madrid man lash home the second three minutes later
Fred (66) then added his own name to the scoresheet with a delightful flicked finish at the near post
 It came a minute after former Liverpool striker Andy Carroll (65) was sent off for a second bookable offence, having made a late, clumsy challenge on Casemiro
Reading pulled back a goal late on through Amadou Salif Mbengue's (72) free header, but the only real blow for the hosts was an ankle injury for midfielder Christian Eriksen
Ten Hag, who faces a hectic fixture schedule next month with eight matches in February, says it is "difficult" to give a diagnosis but the midfielder will be assessed over the next 24 hours
United now join the likes of Manchester City, Tottenham and Leeds in the fifth round, with the draw being made on Monday evening
Man Utd began well against their Championship opponents and had three openings inside 15 minutes
 January signing Wout Weghorst saw his neat flick blocked, before Eriksen sent a free-kick just wide
 Then, Marcus Rashford saw his won set-piece well saved by Joe Lumley
Antony looked bright in the first half too, but could not send any of his curling efforts on target
 The winger set up Bruno Fernandes, but he also curled an effort just past the post
 The two linked up again just after the half-hour, but Fernandes dragged a shot well wide
Rashford thought he had fired United ahead soon after, scrambling the ball over the line from a tight angle, but VAR intervened to rule it out for offside
 Weghorst was the culprit, off by a knee as he nodded a looping ball down for Rashford's finish
Reading almost went into the break 1-0 ahead
 Tyrell Malacia was caught dawdling on the ball by Royals skipper Junior Hoilett, who hurried the young full-back into making a pass
 However, Hoilett's scuffed shot was saved by David de Gea
Man Utd finally made the breakthrough shortly after the break with a quickfire Casemiro double
 The first saw him set up superbly by Antony, with the winger cutting past a defender before slotting the ball down the channel for his team-mate
 It was then a delightful dinked finish from the midfielder, taken with real skill
Three minutes later, and another moment of quality from Casemiro
 Newly-introduced substitute Fred laid the ball off for his fellow Brazilian, who had all the time to prepare his shot before sending a thunderbolt past Lumley
 It took a deflection on the way through which may have wrong-footed the goalkeeper, but it was another fine goal nonetheless
Reading's evening went from bad to worse with Carroll's red card in between the second and third goals
 Having already been booked earlier in the game, the frontman flew into a rash challenge on Casemiro in midfield - very much a striker's challenge - before being shown a second yellow card
And it did not take long for United to add a third
 Fernandes found Fred at the near post, before the midfielder flicked home past Lumley as the hosts threatened to run riot at Old Trafford
Reading were handed a lifeline when they pulled a goal back just after the 70-minute mark
 It was a goal that will have annoyed Ten Hag with Mbengue allowed through the defence to nod home with a free header
However, that was the only real scare Reading were able to muster as Man Utd cruised into the last 16
Antony has provoked a lot of ire since signing for Manchester United
 The Brazil winger's showboating and inflated price tag have made him an easy target
But after a frustrating start to his career at Old Trafford the 22-year-old is slowly beginning to show why Erik ten Hag was so insistent on bringing him to Manchester
"I think he's growing," Ten Hag told 
 "We want him to be more dynamic, variable and direct
 Today was a lovely pass for the first goal
"We are happy with his improvement in this moment
 There's big potential in him and he has to develop it every day
"Antony, who has scored six goals for United this season, showed his threat as a creator against the Royals
The former Ajax winger, who cost £86m in the summer, created more chances than anyone on the pitch at Old Trafford and set up his Brazil team-mate Casemiro for the opener with a slide-rule pass
United fans can expect more frustrating evenings with Antony, but he brings much-needed balance to their lopsided attack on the right wing and is an asset out of possession
Ten Hag has laid down the gauntlet for Antony to prove the doubters wrong and become a key figure in his rebuild at Old Trafford
"The first 60 minutes was really good
 We totally dominated
 We were composed with good moments
 In the first half we had some good opportunities
 I don't know why the [Marcus Rashford] goal was disallowed
"We are here for trophies but we have a long way to go
 We're building
" "We know he's a great player
 In Madrid's midfield with Kroos and Modric it was great
 I think he's capable, you see offensively he enjoys it
 What I like is dynamic football with variations, many position switches
" "I think he's growing
 We want him to be more dynamic, variable and direct
 Today was a lovely pass for the first goal
"We are happy with his improvement in this moment
 There's big potential in him and he has to develop it every day
""He's been a huge signing
 Over the last few years for Man Utd, particularly in the middle of the park, they've lacked a quality player with a big personality, a guy with a bit of presence
"He's a top-quality player
 We see it week, in week out
 He affects games
"Before he came there was this perception he's a sitting midfielder because of working with different players at Real Madrid, players who are more attack-minded, but we're now seeing over the last few months he's got so much quality going forward in terms of the final pass and he's getting goals, as well as being very, very good defensively
