Why man utd win and chelsea lose this year

based on bbc sports it is divided into 6 main factor.
first ,SOLID AT THE BACK
Chelsea are a brilliantly organised team who remain extremely difficult to break down.
they got 21 clean sheet compared to man u 15.
but chelsea over-stretched defensively - particularly in the centre.William Gallas and Robert Huth left the club last summer while John Terry, Ricardo Carvalho and Khalid Bouhlarouz have all missed games through injury.
Influential skipper Terry missed a crucial eight weeks of the season during December and January. And it is no coincidence that Chelsea conceded twice in each of the first four games Terry missed over the Christmas period.peter cech injury further worsening the condition.
For man utd ,Edwin van der Sar make a good keeper and Serbia defender Nemanja Vidic has also enjoyed a fine season in the centre of defence, with his no-nonsense defensive style complementing Rio Ferdinand's make man utd defence diff to break.

good middle
scoles returns after long injury with prtner carrick make flow of attacks supreme.
Micheal ballack failed to coordinate with lampard well. I think next year the partnership will be improve for chelsea.
WORKING OUT WIDE
United boss Ferguson understands the importance of width and in the evergreen Ryan Giggs has a veteran winger who is both consistent and potent plus the maturity of C.ronaldo makes them strong.
FINDING THE NET
drogba for chelsea with 19 goal proves that he already adapt to chelsea. but top scorer in milan Andriyi Shevchenko has endured a difficult first season in England. Maybe he will improve next year. Man utd got too many player who can score .it includes Louis Saha, Wayne Rooney, Henrik Larsson, Giggs and Ronaldo . so very difficult for defence to mark them.
HARMONY AND HEARSAY
relationship between Mourinho and Abramovich has been the subject of constant speculation.Abramovich is said to have favoured a more attacking style of play and wants to win the Champions League above all else.While man utd now in the hands of Grazer not interupt much on football management.
WINNING WAYS
United lost just one of their first 17 fixtures, drawing two and winning 14.

During the same period Chelsea lost two and drew three, winning 12 to give United a five-point lead.

Chelsea won nine straight games starting on 31 January - their longest winning streak of the season. United responded with seven consecutive victories of their own before losing to Portsmouth. but chelsea lose momentum by draw to new castle and bolton.

with the above factor, man utd win the title.
For me, Jose Mourinho is the good manager if abramovich not interrupt him . As a boss , you shouldn't buy player according to your interest but must based on manager preference. i think chelsea will be a hard shell if mourinho is giving the authority and shechenko will play a better game .

a 1-1 draw + champion for man utd

a good games played by arsenal and a lot of superb save from lehmann secure a draw for arsenal.Chelsea found themselves a man and a goal down after Khalid Boularouz was sent off for fouling Julio Baptista. Gilberto Silva put away the penalty .Chelsea still manage to pull a equiliser with one man down by a header from essien. they failed to score a winnin g goal.
It means a champion for man utd. Boss Sir Alex Ferguson has won the Premiership nine times during his 21-year reign. A remarkable record for him. Although man utd loss 3-0 to milan. They still proved they are the strongest in primier league.
