I like the idea of Rooney, Giroud and Sandro fighting for two starting places.
Giroud adds a slightly different dynamic to Rooney or Sandro.
I think its strange that Arsenal will let him leave for "only" £20m, considering he's ahead of Lacazette in the pecking order for the French national team.
Barkley and Lukaku
or
Rooney and Giroud
Not convinced that's a step forward personally - hoping Sandro can tear it up/we bring in another striker.
