I think Sam thinks if you put a couple of attacking players on the pitch then goals just....happen.
It's known as the Ronald Koeman gambit.
And this is exactly the way the club is being managed w/r/t recruitment. It's why I'm such a grump all the time. It's not a viable strategy and things are never going to get better if we keep trying different versions of the same crap transfers over and over.
It's way more important to have midfielders and wingers who know how to work the ball into dangerous areas. Tosun and Walcott address none of our attacking problems, however good their respective records are.
