Young has a better goals and assists per minute ratio than Bale, Nani and Valencia AND he's had the most injury hit season and he's the only player out of the four at a new club, playing with new players, settling into a new life, with both injuries upsetting his season and more off the field trouble(breaking up with long term finance who he has a kid with?).
With Nani, he's actually played a lot more than most people think this year, he's just not been memerable.
He scored against City in the Community who gives a damn, he then got a goal against Arsenal(who didn't), a goal and assist against Chelsea still in September, and from mid september till the Everton game he didn't score or assist against the top half of the table(ok, I can't remember if Fulham were top half at the time but, away from home Fulham barely count as a premier league team

).
People don't remember Nani's contribution as he's had relatively few games where he's contributed, 2 goals and an assist, or the other way around against Wolves, Fulham, 2 assists against Bolton, one against Villa.
He's simply not performed against top teams this year at all.
Valencia has 11 of his 13 assists against, Villa, Wigan, Wolves, Blackburn, QPR and Fulham. 3 of his 4 goals were Blackburn, Wigan, Wolves. To suggest he's a bit of a flat track bully isn't unfair.
he was woeful against Barca, he was very poor yesterday, he was poor against City, Everton, the tougher recent games against Wigan.
Bale sucks, he thinks he's Messi, in reality he's closer to Kilbane with real pace

He's selfish, shoots loads, scores little, wastes a huge majority of his crosses and doesn't know where the left wing is anymore, inconsistent and meh. THe biggest reason Spurs push for 3rd faltered and let Arsenal gain 13 points back on them, was Bale getting big headed and thinking he could carry the team himself.
Let's look at who Bale got his contributions against, West Brom twice, Bolton three times, Stevenage, Norwich, Wolves, Stoke, QPR.... (sounding familiar), Villa, Wigan, Hearts..... uh oh. Of his 10 assists, ONE was to Chelsea, another West brom(if the count as top half) all the rest to bottom half teams(and most of those against the bottom 5. Goals, 1 against City, one against Chelsea, he was gash in both games, the team lost both games, the rest of his goals, all bottom half, mainly bottom 5.
As for other posts, claiming Cleverley cost you the title is just daft, he has promise, you haven't played him for a full season before nor since his first half dozen games, has he looked anywhere near as good(when the team has been playing worse football).
Vidic, again few if any of your problems this year have been at CB, Evra would STILL have played alongside Vidic and he has been by far the most culpable person in defence.
Arsenal could have played Kompany and Vidic, and it would still be Song's lack of tracking back that cost us soo many games because HE is the one responsible.
If Evan's had been responsible for most of the goals conceded, you'd have a point, however most of the teams problems have occured upfront with first choice team out on the pitch, or at left back with first choice player. CB's can't do anything when another defender leaves them out to dry, which Evra has done for two years.
injurys to AV, is madness, as above, he's been poor, the games he does well in(less good teams) he was available, he played in almost all the games you've dropped points in since xmas.......
Fletcher, describing a guy who has barely played, who stopped playing till his health problems clear up(which they may never) as semi retired is inaccurate?
Scholes FULLY retired this season... and has played more games than him.......
Anyway, Fletcher simply isn't that good, he's a midfield spoiler, that's why you play Park, Fletcher had one really successful season doing that, it wasn't last year, or the year before, and certainly not this year.
