We have money for one massive transfer at best and that should be a centre forward. LW would be nice, but we still have Fati, Dembele and Griezmann (yeah) for that position. As soon as Suarez doesnt perform (or is injured) we are royally f*****. Every lineup with a worldclass left winger, Griezmann and Messi looks much worse than Fati/Dembele/Griezmann-Martinez-Messi on paper. Griezmann is not a lone striker. And to gamble on Fati as a '9' is insane (I really dont see it).
I would also like to see Martinez-Messi-Griezmann ;D
