LW: Ronaldo
ST: Lukaku
RW: D.Costa
With currently, Berna, Cuadrado, Mario, Higuain as subs (some of them could leave) , feels like we would need one more winger, Cuadrado and Berna as alternatives is to bad, imagine Ronaldo or Costa being suspended or injured in a important match.
Also we would rely heavily on Costa to deliver for our attack to be great. I personally don't trust Berna or Cuadrado as starters.
