IT took Ruben Amorim's side just 48 SECONDS to break Manchester United's 33-year duck in his home debut.
It was the first time since 1991 that the Red Devils have scored in the opening minute of a major European game.
The last time United put one in during the first 60 seconds of a European clash was during Sir Alex Ferguson's fifth season.
It was Brian McClair - now 60 - who opened the scoring against Montpellier in a Uefa Cup Winners' Cup tie.
Jonny Evans was just three years old. Casemiro wasn't even born.
But it was now Alejandro Garnacho, 20, who got United off to their dream start - albeit from a Bodo/Glimt goalkeeping howler.

Garnacho was the one to put the ball in the back of the net - but the goal was all about the hard work of Rasmus Hojlund.
He dispossessed the Bodo/Glimt stopper, who took far too long on the ball in his own box before trying to wrestle Hojlund down.
It was another fast-start under Amorim, just as we saw at Ipswich.
But that quickly unravelled 19 minutes later when the visitors - from Norway's top division - pegged one back through an absolute screamer.

It was blow for Amorim, who you could see becoming frustrated that his side couldn't capitalise on their dominance.

Man Utd ratings vs Bodo/Glimt
MANCHESTER UNITED beat Bodo/Glimt 3-2 as Ruben Amorim made his Old Trafford bow.
The Red Devils made the dream start as Alejandro Garnacho scored after just 48 seconds.
But Bodo/Glimt hit back with two quick-fire goals before a Rasmus Hojlund double saw the Norwegians off.
It marks Amorim's first win as Man Utd boss following his 1-1 draw with Ipswich on Sunday.
And Bodo/Glimt incredibly turned the game on its head just four minutes later as the Norwegian outfit went 2-1 up.
Forest winger Zinckernagel outpaced Tyrell Malacia, who looked every bit a player who hasn't taken to the pitch for 550 days.
Malacia, who was later hauled off at half-time, had a headstart but you wouldn't have known it as Zinckernagel fired in a low effort that squirmed in under the legs of Andre Onana.
Goalscorer Garnacho continued to work as part of the front three - a a shift from his wing-back position during Sunday's 1-1 draw at Portman Road.
Hojlund levelled the scores on the brink of half-time with a superb right-footed volley - his best goal in a United shirt.
And it took just five minutes after the break for the Dane, 21, to put the home side back in front with a sliding finish.
United are up to 12th in their European league phase table, with three games remaining.
Ferguson was in attendance at Old Trafford for Amorim's first home game as Erik ten Hag's replacement.
The cinema quickly panned to the Scot, 82, after Garnacho's opener.
Meanwhile, Amorim slashed two names off his United team-sheet for their Europa League clash.
