if Son or Bergwijn can play up front (they've both done it numerous times), why can't Bale play behind them in a 4-2-3-1 or next to them? To me, that's a very dangerous attack, with Dele, Lucas, Lamela, Sess, GLC able to play with them.I think he could play in a front 3 out on the wing but I don't think he solves any issues we have with giving Kane time off.
For example, he is not starting as a lone striker in Europa League games or Cup games. He isn't an option to play as a lone striker or really even in a partnership with Son if Kane is injured for multiple games.
I think if we bring him in we definitely still need a true striker to be brought in to at minimum play the Europa League games and early round Cup games. Bale doesn't fill that need.
You may be right, i'm just looking at possibilities. I get that he may not be thrilled to play those lesser games.
