However, they still have Raphael, Torres and Fati but it is true that they will lack some creativity and speed when the aforementioned players are missing.
These two players are not as good as Pedri and Gavi, so Barcelona's style of play will automatically be slightly different, it will be interesting to see how the second leg goes at Old Trafford with a slightly different scheme and game.
That's why Weghorst is considered important to be in the line-up every time Manchester United plays, because Erik Ten Hak understands very well what makes his team grow although the goal did not come from a centre-forward. In the philosophy of football, victory is very important because what is seen is not who plays well and scores goals.
That is why I did mention Weghorst's work rates in my post. From time to time it happens that nobody understands why a coach picks a certain player, but it might be the perfect missing piece to complete the idea the coach in mind. I remember when Mourinho was a fan of Khedira, you remember too? I didn't ever like Khedira, but Mourinho must have had his reasons to let him player a full season. The work rate was great again but he wouldn't hit the target from two meters even if the goal was empty. Players with high work rates have a value that is as important as goals and assists.
