They signed Wirtz as an attacking midfielder not as an striker. He is there to create chances for Liverpool. Liverpool needs to get an another striker that scores goals to help out Wirtz. I dont think liverpool can sign Isak due to his high fee. So they will need to go for a cheaper option
Florian Wirtz can play as a winger or a midfielder. But surely he won't play as a striker (CF). Considering the current players in Liverpool attacking, I guess Arne Slot will put him in the line up as an attacking midfielder or as a left winger. These are 2 positions that can optimize the capability of Florian Wirtz.
According to the latest news, Liverpool targeted to sign Osimhen or Gyokeres. It seems they stop to negotiate for Isak. Yep, Isak may be overprice and it doesn't fit with the capability of the player. Osimhen or Gyokeres should be a better choice for Liverpool new striker. Let's see which striker to be signed, I am sure Liverpool will choose the strongest one.
