"Wayne was ready to play, he was a big option".
That goal would prove to be enough, as United went on to claim their second Europa League trophy.
"Yesterday morning, we were devastated", said United midfielder Ander Herrera, dedicating the win to the victims.
"They will learn a lot from it and we will become stronger, and if we can keep this squad together we will be stronger next season, for sure", he added.
Paul Pogba's deflected shot put them ahead in the 18th minute and Henrikh Mkhitaryan's sixth Europa League goal of the campaign, flicked in from Chris Smalling's header at a corner, confirmed they would add to the EFL Cup won against Southampton earlier this season.
He was the first to collect his medal and took a moment by himself to kiss and hug the trophy having been made the subject of the loudest cheers from the Manchester United fans.
"Obviously I'm disappointed, because you play finals to win them", Bosz told a news conference at the Friends Arena.
Ajax, fielding the youngest starting lineup in a European final, were expected to make a quick start as they did in their 4-1 win over Olympique Lyonnais in their semi-final first leg.
The club captain has been heavily linked with a move away when the transfer window reopens and Mourinho brought him on for the closing stages of this evening's 2-0 win over Ajax in the Europa League final.
For United coach Jose Mourinho, it was obvious that the victory was a huge weight off his shoulders, because of both the emotions of the last few days and the importance of the match.
Defeat would have left heavy gray clouds hanging over the club - another season in the Europa League, more Thursday night games, the prospect of missing out on priority summer targets such as Antoine Griezmann, Romelu Lukaku and Andrea Belotti.
The victory means United have won every European club competition and will compete in next season's Champions League competition.
Talk, nearly immediately, after the win turned to the prospects for next season and what Mourinho's plans for the summer will be.
"We wouldn't think twice".
The planned pre-match one minute's silence, in honor of the victims of the blast, rapidly turned into 60 seconds of applause, during which United's fans chanted poignantly "Manchester, Manchester" for the first time. "People who respect their opponents and exploit their weaknesses".
