Manchester United’s dismal season hit a new low as Brighton condemned them to a 4-0 defeat, while Chelsea blew a two-goal lead against Wolves.

Rangnick’s team were stunned in the 15th minute when Ecuador midfielder Caicedo scored his first goal in English football.

Alex Telles made a hash of his clearing header and Gross’ shot was blocked to the 20-year-old Caicedo, who smashed a 25-yard rocket into the bottom corner.

United had failed to muster a single shot on target in a terrible first- half performance.

Fred and Edinson Cavani were sent on to replace Anthony Elanga and Nemanja Matic at the break, but United were unable to raise their game.

Just four minutes into the second half, Cucurella cried tears of joy after he joined Caicedo in scoring his first goal in English football.

United paid the price for awful defending as the Spanish defender was allowed to run onto a cutback and drive his shot into the roof of the net.

In disarray at the back, United were breached again in the 57th minute.

Cucurella fed Trossard and he had space to tee up Gross inside the area for a cool, flicked finish past David De Gea.

United had totally lost the plot and Brighton piled on the misery on the hour mark.

It was a farcical goal that summed up United’s decline.

Diogo Dalot tried to clear off the line from Danny Welbeck, but the ball hit Trossard and trickled into the net, with VAR awarding the goal after a check for handball.

Furious United fans taunted their players with chants of “You’re not fit to wear the shirt” and “We want Ten Hag”, to which Albion’s supporters responded by bellowing “We want 10” in reference to their goal spree.

It could almost have been that bad, but Alexis MacAllister hit the post and Welbeck curled wide as United surrendered without a fight.

Meanwhile, earlier in the day, Chelsea blew a two-goal lead in front of prospective owner Todd Boehly as Wolves snatched a dramatic 2-2 draw, while Watford were relegated from the Premier League after defeat at Crystal Palace on Saturday.

Romelu Lukaku, who has endured a wretched season following his £97-million club-record move from Inter Milan, converted a VAR-awarded penalty after he was fouled by Romain Saiss in the 56th minute.

The Chelsea striker followed his first Premier League goal since 29 December with another two minutes later.

This time he produced a fine 20-yard finish from Christian Pulisic’s cross as Boehly rose from his seat to celebrate.

But Wolves forward Francisco Trincao set up a tense finish when he hammered home from the edge of the area in the 79th minute.

And Chelsea cracked deep into stoppage time as Conor Coady nodded a close-range equaliser to leave Boehly shaking his head in frustration.

Chelsea are six points ahead of fifth-placed Tottenham, who play their game in hand at quadruple-chasing Liverpool later on Saturday.

At Selhurst Park, Watford needed a win to keep alive their faint hopes of avoiding the drop, but Wilfried Zaha’s first-half penalty was enough to condemn them to relegation.

With three games still to play, second-bottom Watford are certain to drop into the Championship 12 months after winning promotion as second-tier runners-up.

The Hornets will head into the close season looking for a new boss after their current manager Roy Hodgson confirmed he would not be extending his short-term contract.

Hodgson (74) was unable to rescue Watford after replacing the sacked Claudio Ranieri in January to become the club’s third manager this term following Xisco’s dismissal in October.

Watford were heading for relegation in the 31st minute when Hassane Kamara handled Michael Olise’s header, conceding a penalty that Zaha converted for his 14th goal this season.

Burnley wasted a chance to boost their survival chances as Aston Villa cruised to a 3-1 victory at Turf Moor.

Caretaker boss Mike Jackson saw Burnley beaten for the first time in five games since replacing the sacked Sean Dyche.

Former Burnley striker Danny Ings put Villa ahead in the seventh minute with a composed finish from Emiliano Buendia’s pass.

Buendia slotted home from Lucas Digne’s cross in the 31st minute.

Ollie Watkins scored Villa’s third with a diving header in the 52nd minute and, although Maxwel Cornet struck for the hosts in stoppage time, Burnley sit perilously just two points above the bottom three.

Burnley would be back in the relegation zone if third-bottom Everton beat Leicester on Sunday and fourth-bottom Leeds avoid defeat at Arsenal.

Brentford crushed Southampton 3-0 at their Community Stadium, with the goals coming from Pontus Jansson, Yoane Wissa and Kristoffer Ajer.
