I think eras have changed and in this era of Erik ten Hag I'm sure Manchester United will be able to play well, even though Barcelona might eventually win but this match will still be interesting to look forward to. Also, regarding the players or squad that Barcelona have, basically they already have players who have good quality, so even if one key player is injured and or cannot be played, of course Xavi will be able to use other strategies by adjusting the available players.
So yes, this match will of course still be interesting but one thing I still believe in, it looks like Erik ten Hag will be able to make the right strategy in this match to make Manchester United qualify for the next round.
Erik Ten Hag's is showing good signs of a better future for the club. He has made quite an impact in the team and the players now understand the task and objectives of the manager and are showing this character on and off the pitch. Manchester United are playing much better football and will certainly give Barcelona a tough one to contend with when they go head to head in the Europa league play offs.
