Ten Hag can't find any star striker at the moment. He kept Ronaldo in his match plan. And that's why he didn't take any substitute player for Ronaldo. But Ten Hag should have taken Ronaldo's alternative player in the team. Even if Ronaldo gets an offer from a renowned club, he will leave Manchester United. Despite having enough funds, Ten Hag did not bring any new star players to the team.
Erik ten Hag relies more on young players who are full of energy and motivated to achieve great results. He used to work like this in Ajax, and it seems that he hopes that the same scheme will work for him at Manchester United. Ronaldo is a professional and he will score goals, it’s more a question of what kind of relationship Ronaldo and the team will have, because if can believe the rumors, then Ronaldo’s agent was actively looking for a new club for him. And this is already a signal for ten Hag that he needs to look for a replacement and the sooner the better.
