Erik ten Hag&aposs side were comfortably beaten by the Magpies, with goals coming from Miguel Almiron, Lewis Hall and Joe Willock. Both sides had made several changes but United suffered the same problems that they have done all season.
Supporters were somewhat boosted by the return of Aaron Wan-Bissaka, who came off the bench at half-time, but Raphael Varane missed the clash through illness. Casemiro, hooked at half-time, picked up an injury that will see him miss the weekend trip to Fulham.
RATINGS: Dalot and Martial awful in defeat to Newcastle
Here are your moments missed from another woeful night.
Old meets new
Martin Dubravka was back at Old Trafford as he started for Newcastle, returning to the club where he spent half of last season on loan. The Slovakian goalkeeper enjoyed all the usual pre-match tunnel niceties, sharing a handshake and hug with Andre Onana.
Dubravka was unfortunately cup-tied for last season&aposs final, having played twice in the early stages of the competition for United. And that led to the incredible scenario of Loris Karius making his debut for the Magpies at Wembley, with Nick Pope suspended.
Fans exchange verbal blows
Newcastle brought 8,000 fans with them and they enjoyed every second of an excellent night from their perspective. There are fewer limitations on away capacity compared to the Premier League and that meant that some of the more vocal home fans were relocated to near the expanded away end.
And for the opening exchanges, there was a lively atmosphere with the jovial home support singing &apos2-0 in your cup final&apos – a very literal reference to the defeat at Wembley last season. However, the travelling support didn&apost take long to get the upper hand, bringing out &aposYou&aposre getting sacked in the morning&apos and &aposAre you Sunderland in disguise?&apos after Almiron gave them the lead.
Newcastle doubled their lead through Hall&aposs accurate volley close to half-time, following a swift counter-attack that came from a free-kick in their own half. Referee Robert Jones blew for the free-kick and heard moaning voices coming from Anthony Martial, Mason Mount, Harry Maguire, Hannibal Mejbri and Casemiro.
But while they were all looking at the referee, Sean Longstaff trotted towards the dead ball and sprayed a pass out wide, kicking off the attack that would eventually see the ball end in United&aposs net again. The replays do not look good for those players.
Hannibal geeing-up the crowd
Hannibal was lucky to make it beyond the first 20 minutes. The Tunisian is never one to shy away from the physical side of the game but was booked for barging Longstaff before arguably committing two or three more bookable offences before the break.
United came out for the second half and were pushing for a goal in the opening minutes, and Hannibal rallied the home support after winning a free-kick in a dangerous area. Old Trafford responded but Mount didn&apost, the midfielder swinging in a dreadful set-piece.
