Yet of a competition that dates from the 1960-61 season, he said: "Could the English football survive or even be better without this competition?"
"Maybe we would be fresher for European competitions, for example".
As for the matches played by Burton Albion, it's not good to call them successful. If a player does the job for him he has him in and if he doesn't that's it.
Here's a look at the key talking points for Jose Mourinho's men ahead of the encounter. He was able to walk off and head straight down the tunnel alongside a physio, but such is his growing importance that Mourinho was not in the mood to take any chances.
United's reward for beating Burton is a trip to Swansea in the fourth round, with Mourinho happy to come through the Carabao Cup tie without any injury concerns or cards. Next in a seemingly endless medley of chances, Mata hit Ripley's left post, Matteo Darmian collected the loose ball and found Martial, but his volley ricocheted away. And the Italian full-back has warned they must not pass up the opportunity to impress Mourinho with fierce competition for places at Old Trafford. We have a genuine superstar here - a baller in the truest sense of the word - and he is only getting started.
There was also a first appearance of the season for Luke Shaw, who came on for Juan Mata at half-time and lined up at left wing-back. The Frenchman finally got his goal after Rashford freed him up with a delightful through ball.
A Dominic Calvert-Lewin double relieved the pressure on Everton boss Ronald Koeman as the Toffees dispatched struggling Championship side Sunderland 3-0 to set-up a showdown with Chelsea at Stamford Bridge.
There was no let-up from Mourinho's men, with the impressive Martial brilliantly working an opening before having an effort saved.
"Not everybody is born at 16 years old ready to go straight into the Premier League and they're physically ready". Of course, David and Bailly aren't playing but if you go to the next round probably these guys play and I give rest to others.
