Since it's late, I'll limit to thoughts on the Europa League final. It's going to be very interesting. As noted, Ajax are full of youth and desire, and it will be interesting to see how their early action impacts the typical Mourinho plan, should he institute it. This is it for the campaign, so Ajax is going to give it everything, just like Celta Vigo did against United in the return leg of the semifinal. If they stay true to form under Bosz, they will press, they will attack. If they run with impunity and get an early goal, it will be interesting to see how the match proceeds from there.
United can't be content to go with a premeditated plan to just try to hold, get the odd counter, and capitalize there. That assumes too much. There can be no assumption that Ajax will crumble under pressure or that their youth will fail them in the environment of the final. There's really more pressure on United in the context of the 17/18 Champions League, as Ajax have already qualified (third qualifying round start) via their runner-up finish in the Eredivisie. A victory for Ajax would just give them a nice trophy and upgrade them to the group stage, so they can feel a bit freer. Mourinho having punted early on a top four placing in the Prem, all United's eggs are in this basket. (I agree that sixth place with a major trophy is better than fourth without that same trophy, but I think that even with the schedule they could have had fourth in the Prem and still made this final. I'm not the manager, though.) There can also be no assumption that United will simply cash in well on their chances, as there have been many matches in the Europa League and the Prem where that has just not happened.
Flexibility is key for United. Mourinho knows how to be flexible, but there have been some times that he's been arguably a bit late on making the personnel changes that need to happen to claw back a match or pull out the win. He has to be as willing to attack from the beginning as he is to park the bus. He's been here before, though, and knows that well. There are youth and pace in the United squad as well, and I think their starting XI will be as balanced between those qualities, experience, and guile, as Mourinho can manage.
The Manchester Arena attack, as much as one would like not to mention it, cannot be ignored. The United players, as professionals, will work hard not to be overcome by that aspect, though there is no doubt now that part of the mission is to win not just for the club and its supporters, but for the city they represent, which has suffered so greatly. The match lead-up will be impacted, and it will be interesting to hear what is said after the match is done, win or lose.
In the end, I think United will probably prove too much for Ajax to handle, but it should be a good match. Most of their major players have had some good, or at least adequate, rest, and players and manager all know that this match will require their very best, which is better than most teams in Europe. In about 12 hours, we shall have a much better idea of how it all rates as far as this championship.
