I admire your confidence (and you may be right), but I don't share it.
Last year, it was , "RVP, Di Maria, Rooney, falcao" and we struggled just as we did today.
Given that it took 60 minutes to get a shot on goal today, IMO, we need to change the system. Our system of play is what is holding us back.
If you cant score goals with Di Maria, Rooney, RVP, Depay, etc, then its difficult to blame the players.
To compare further (using stats):
Leicester, for example scored 4 goals today.
We have scored 4 goals in our last 7 games.
Lets also not forget that our real problems occur in away matches and when teams park the bus. Today Spurs didnt park the bus and it was a home game.
The real test will come next week against Villa.
In saying all of the above...it is still the start of the season, so even though I sound negative, I am currently neutral.
