I think with Son & Mouras versatility that we won't be seeing 3 out and out senior strikers in our ranks for some time.In my mind ideally we would have 3 "pure" strikers. Harry, An older veteran (Llorente, Rondon, pick your poison) and a younger understudy to learn from both. That combined with having Son and Lucas and any potential other flexible winger/AM that we have would make for a strong attacking line.
I can see us getting another wide forward before we get another striker through the door. We all know Poch loves a player who can mix it up in different positions
