Jesus, People like to rewrite history here. Ronaldo will not magically increase the chances of United to win trophies any more than they already are, the forwards, Van Persie in Particular, are doing a fantastic job but people are so blinded by their strange love for this guy they're willing to "fix" what isn't broken.
Goals scored by United in the seasons Ronaldo became world class:
06/07 83
07/08 80
08/09 68
Goals scored by United the seasons after Ronaldo left:
09/10 86
10/11 78
11/12 89
12/13 54 (20 games)
Now, United team post Ronaldo has outscored the team with Ronaldo in it EVERY season save for the 2010/2011 Season. I mean, half way through this fecking season the team is only 16 goals away from the goal output of the team in the entire 08/09 season, yet bringing Ronaldo back will make the team score a gazillion goals, right?
Van Persie is matching Ronaldo's output at United and he is doing it brilliantly without demanding the ball 60% of the time. The team's attack is at the best it's ever been since the 98/99 season, yet people are in favor of swapping extremely important players and a feck load of money to bring a player that fecked off to his "dream club" the moment they came calling.
But oh no, it doesn't matter because Ronaldo will win us the Champions league, Really? Since 2006, Ronaldo has won a grand total of 1 CL title with teams that are AT LEAST the second best team in the world on paper at the time(United and Madrid), yet he'll automatically transform United into treble winners right? But yeah, don't let facts get in the way of a good old romantic story and all that jazz, Christ!
