To be honest, I don't want to discourage United fans, but with the current situation and condition of United's game, it will be difficult for the Red Devils to win their last two matches in the Champions League group phase. Then, will they finish in 3rd place to have a ticket to the playoffs of this competition? There is very little hope, even though in football it is always difficult to predict. There is no other way, apart from just following their progress in every match, especially in the Champions League.
As for Sevilla, it seems their fate will end the same as United.
Now, they are at the bottom with only 2 points. as for the match against PSV, it is not certain that Sevilla will be able to get out of the pressure and win the match. Apart from that, the last match will be at Lens headquarters. What is certain is that this team's chances are not like last season. It is very likely that Sevilla will resign in the Champions League group phase and will not have the opportunity to appear in the Europa League competition. but, as I said, in football it is unique. We'll see, every match they play
Man United is having a pretty bad season to date and they have lost their bottom players as solid defensive guards, so Man United's chances of qualifying for the round of 16 will be much more difficult. Losing Eriksen and Hoojlund will certainly affect their performance on the front lines, even though this season Erik Ten Hak has not given Eriksen the opportunity to start. Visiting Galatasaray's headquarters was not an easy match because Man United looked so inconsistent when playing at home and even had to accept a 2-3 defeat in front of their own crowd.
Their final match in the group phase will be against Bayern Munich at Old Trafford and perhaps at that time Man United will still not be able to field several important players in defensive positions. Realistically, Man United may have to fight to qualify for the Europa League rather than aiming for the runner-up position which is much more difficult. Likewise with Sevilla, their chances of playing in the European league are currently still quite difficult because they have two tough matches that they have to play in the future.
