Birmingham: Philippe Coutinho made a dream debut for Aston Villa as the Brazil star's late equaliser capped a thrilling fightback from two goals down against Manchester United in Saturday's 2-2 draw.
Four years after he last played in the Premier League with Liverpool, Coutinho made an instant impact on his return to England following his loan move from Barcelona this week.
Coutinho came off the bench midway through the second half with Villa trailing 2-0 after Bruno Fernandes's double for United.
The 29-year-old provided the assist for Jacob Ramsey to give Villa hope with 13 minutes left.
Coutinho then converted Ramsey's cross five minutes later to ensure Steven Gerrard's side made amends for their FA Cup third round exit at United on Monday.
Coutinho suffered a disappointing time at Barcelona, but Gerrard was confident he could bring the forward back to his best after playing with him at Liverpool.
The early returns look promising, although United will be kicking themselves for letting the game get away.
United have now gone two league matches without victory after losing to Wolves in their previous top-flight game.
With United languishing in seventh place, there will be fresh questions about interim boss Ralf Rangnick.
Rangnick had already endured reports that United's players were unimpressed with his coaching methods and his backroom staff.
This collapse will hardly ease the gloom around United, with their late meltdown taking the gloss of Fernandes's return to form.
Fernandes owed his first goal to a howler from Villa goalkeeper Emiliano Martinez, who let his free-kick spill into the net.
The Portugal playmaker's second goal was the kind of eye-catching finish that made his name when he arrived at United from Sporting Lisbon in January 2020.
But United couldn't hold the lead in another blow to their bid to qualify for next season's Champions League via a top four finish.
Cristiano Ronaldo was absent from the United squad after the Portugal star was unable to train on Friday due to the hip flexor injury that also forced him to miss Monday's FA Cup tie.
United made the perfect start thanks to Martinez's blunder in the sixth minute.
Fernandes' 25-yard free-kick left Martinez red-faced as the Villa keeper got both hands on the ball, only to let it drop through his legs and trickle over the line.
Martinez may have been slightly unsighted by United striker Edinson Cavani as he stretched to make contact with the set-piece, but it was still a horrendous mistake.
The former Arsenal keeper partially redeemed himself when he charged off his line to block Mason Greenwood's close-range effort.
Alex Telles tested Martinez's nerves with a swerving free-kick, but this time he saved well.
David De Gea preserved United's lead with an instinctive save from Emiliano Buendia's thumping header.
Lucas Digne made his Villa debut after signing from Everton this week and the French left-back was denied a dream start when De Gea turned away his rasping strike.
De Gea plunged to his right to keep out Ramsey's low drive after his exchange of passes with Morgan Sanson carved open United's defence.
United doubled their lead in the 67th minute when Fred seized on Sanson's wayward pass and fed Fernandes, who blasted a ferocious finish into the roof of the net from 12 yards.
But Coutinho came off the bench moments later to completely change the tone of the match.
It was Coutinho whose incisive pass found Ramsey in the United area, giving the midfielder the chance to fire past De Gea from close-range in the 77th minute.
With Villa Park rocking and United suddenly in disarray, Coutinho raised the roof five minutes later.
Ramsey returned the favour with a perfectly-weighted cross that evaded the United defence and gave Coutinho a simple tap-in at the far post.
