I honestly believe that it was going to be better for Manchester United if they brought in Depay. They need a striker. And right now they do have Weghorst. You but I don't believe that he is going to be good enough alone for Manchester United. In my opinion, Depay was going to be a lot better compared to him.
Anyway, I also think the match between Barcelona and Manchester United is going to be hard for both teams to win. But Barcelona should be a better team going into this match.
About Depay or Weghorst I think Erik ten hag has his own opinion regarding this matter. But what is certain is that Weghorst's role in several Manchester United matches has contributed quite a bit so far, even though he doesn't have the speed of a striker but thanks to his anchor body it makes it a little difficult for opposing defenders to guard him and that is what Barcelona's defense line has to watch out for. Often Weghorst's positioning often makes the opponent's defense a little messy and as a striker bouncing the ball for his teammates he has been quite helpful so far.
But yes, because Weghorst is only a loan player and he is already 30 years old, Manchester United will still need players for the long term as well. After all, I personally believe in Erik ten Hag's choice to build a team with the right squad, and although in some people's view Weghorst is still not quite right, the fact is that Manchester United are still doing well so far.
Also regarding the match against Barcelona, of course this is not an easy match for both of them because both have a chance to win because their performance so far this season has been good in the local league.
Regarding long-term players, I think Erik ten Hag will do this in the summer transfer market, considering that today the winter transfer market has officially closed. Both manchester united and barcelona have shown epic performances this season and there is no doubt that the meeting between the two in the Europa League has been eagerly awaited by many football lovers around the world.
