We still don't know how Rasmus Hojlund will perform. If he performs well, it is good for Manchester United. But Manchester United definitely needs an experienced striker.
Marcus Rashford is Manchester United's most experienced striker. And while Rashford is an excellent player, he is only 25 years old. He played very well in the last season. Rashford scored 17 three goals. However, if Manchester United's goal is the title, and if they want to maintain continuity in the Champions League, then they must add experienced players to the team. Otherwise, the team will not be able to survive in the competition.
Just on based of statics we can't give any certificate to any player even Manchester United history is full of blunders and having not quality players after spending huge funds, but now things are completely different they are fighting for the title race and have good squad with just need a quality striker which give them good replacement in any case hopefully Rasmus Hojlund will be done as par requirements because he has already done good in Atlanta as well.
But, now they need to have settled few more issues which are going to hurt them even most chances now with this aggressive approach they will be able to have better results in both Premier League and Champions League but still have some time to fix issues which can create problems in coming days as well.
