*He's constantly saying that this league is by far the toughest he's ever experienced.
**I'm sure he probably believes that but, other than the top 4, that for some crazy reason we did well against, the opposite was in fact true for most of last season, he played the same tactics game-in game-out and the opposition were lining up to neutralise us knowing exactly what to expect.
He also always refers to his opposition as difficult even when it's league two, "it shall be difficult" and a lot of people refer to their current challenge as the most difficult or important, in the world cup he probably said it is the most difficult challenge of his career. This does not mean he is of the opinion English football is superior to non-english football, he can be of the opinion football is just football wherever it's played and the premier league happens to have stronger opposition in the bottom half than other leagues. (That doesn't mean the type of football played by the English is superior to that played by the dutch, spanish, italians or brazilians).
As an example of him exploiting weakness of the opposition, he said of Burnley he is not surprised by the result (Burnley if you remember had the better of us but we scored more than they) because he practiced set pieces prior to the game, we scored twice from set plays, it also was not a coincidence Burnley had conceded more goals from corners than any other premier league team until that point.
That is an example of identifying a weakness in the opposition and practicing to exploit it before the match, he also said of Liverpool at anfield that we beat them at their own game, they didn't expect United to press and win the ball back so quickly. We also trained to counter their high intensity approach, their players weren't bad, they just couldn't get close to the ball.
He has said these sorts of things quite a bit in press conferences, of Fellaini he would use him against the opposition full back if that full back was weak in the air and Young always knew that's where he would be.
It was no different to the netherlands, he said he had a plan to neutralise Messi for example, his strategy against Spain he said they practiced for two weeks, RVP afterwards said the match went exactly how Louis van Gaal predicted it.
He does look to exploit opposition weaknesses, I can't accuse him of lying when he says that because it's evident in the match.
