Paul Pogba propelled Manchester United towards a 2-0 victory over Ajax on Wednesday in a Europa League final rendered heavy with emotion by this week's terror attack in Manchester.

A night that began with a moment of silence, then applause, in memory of the 22 people who died at Manchester Arena on Monday ended with United completing their trophy collection through goals from Pogba and Henrikh Mkhitaryan.

Reminders of the attack were everywhere at Stockholm's Friends Arena, from United's black armbands to the chants of "Manchester!" from their fans, while Pogba, too, was grieving, following the recent death of his father.

Victory enabled United manager Jose Mourinho, who said prior to the game that he and his players were struggling not to think about the tragedy, to bring his maiden Old Trafford season to a successful conclusion.

He had already guided United to glory in the League Cup and despite a sixth-place finish in the Premier League, success in the Europa League means his side will return to the Champions League next season.

United became only the fifth club -- after Juventus, Ajax, Bayern Munich and Chelsea -- to have won the Champions League, the Europa League and the now defunct European Cup Winners' Cup.

Mourinho, a UEFA Cup winner with Porto in 2003 and two-time European champion, has now won all four of the major European finals he has contested.

Ajax were appearing in their first continental showpiece match since the 1996 Champions League decider and fielded a team with an average age of 22 years and 282 days -- the youngest to have ever started a major European final.

Peter Bosz's effervescent team caused United some uncomfortable moments, but without ever threatening to pull off an upset.

- Defiant chants -

Denied a glorious homecoming by a serious knee injury, United's Swedish striker Zlatan Ibrahimovic was present instead as a spectator to see his current side take on the team where he made his name.

Pogba put a volley fractionally wide in the first minute and in the 18th minute he found the target, albeit with a helping hand.

From Marouane Fellaini's lay-off, the French midfielder let fly with a left-foot shot that flicked off Davinson Sanchez's left foot and looped past Ajax's helplessly wrong-footed goalkeeper Andre Onana.

It was the biggest return yet on United's world-record £89.3 million ($115.8 million, 103.2 million euros) investment in Pogba, who celebrated by pointing to the sky.

Moments later, Antonio Valencia stung Onana's palms after a raid down the United right.

The English side then took their foot off the pedal, enabling Ajax to start finding space in dangerous areas, but within three minutes of kick-off in the second half they had tightened their grip on the game.

Juan Mata's corner from the right was headed down by Chris Smalling and with his back to goal, Mkhitaryan held off Joel Veltman to flick the bouncing ball past Onana and claim his sixth goal in the competition.

Onana was called upon to field a header from Fellaini and United goalkeeper Sergio Romero saved from substitute Donny van de Beek.

But there was little to worry United's fans, who continued to defiantly chant the name of their grief-stricken city as the final whistle neared.
