The difference between us and Chelsea today
Team spirit. Their players aren't that much better than ours, our defence kept everyone especially Torres, Malouda and Lampard especially quiet today. However, you can tell our players aren't playing for each other and the club as much as Chelsea were, most witnessed when their first went in.
Unfortunately, the only thing we can do is stick with the same group (INCLUDING THE MANAGER!), and it WILL come in time. Knee jerk reactions get you no-where. Manchester United are a very very average team on paper, but the majority of them have played together for years and as a result sit (quite comfortably) at the top of the table, mainly as a result of the legacy that Ferguson as forged in his time there.
Winning a trophy will help speed this along, but chopping and changing and making 6 or 7 signings each season is counter-productive and will get us no-where fast. Have faith. We have the players, we have one of the most talented managers in the world, and next season we will shine. Half of our team today arrived in the summer, it will take them a season to get used not only to the Premiership itself, but to playing with each other, life in a new country away from family and friends, new tactics and a new set of fans.
To shamelessly steal and tweak a famous movie quote: If we build it, it will come.
Have faith.
