Didn't Manchester United thrash Bayer Leverkusen 0-5? Probably one of the top 4 teams in Germany, behind only Borrusia Dortmund and Bayern Munich. Then draw with Spurs, lose to Everton 0-1 then get beat by Newcastle 0-1, then beat Shakhtar Donetsk.
Sure Everton are a solid top 6 team in England, as are Spurs ( Not on current form but o well ) But last seasons Champions league was an all german final, which would lead to believe that perhaps the better german clubs, are the best in the world. So if Man U can beat the 3rd best team in Germany, which based on evidence last season is home to the top 2 clubs in the world. Then surely they should beat Newcastle / Everton and Spurs.
Regardless of the manager change that occurred at Man U. The fact is upsets happen, one team just doesn't show up the other does. Arsenal get hammered by Villa. Then go on to top the BPL. Upsets happen, if you managed to go 26-0-0 or heck even any season unbeaten you should be proud. You can put yourselves in same royalty as the Arsenal Invincible's.
And about possession Crystal Palace 27% Everton 73% 9 shots vs 15 shots. While I support Everton, I firmly believe Palace deserved to win that game. Yet it was 0-0. Possession doesn't matter, its what you do with it that matters.
