Well... clearly Vidic is very essential for MU in order to win the division.....

Well...... in February.. Man. Utd have played 5 matches in the league.... and from 15 points available in those 5 matches.. they only managed to grab 6 of them.... in percentages just 40% which is very poor by their standards.... and from this record... as a result.. the title races is wide open.. (BPL)  and there is a big chance for Arsenal to take on the advantage due to this poor form run by MU.... and ultimately,,, end their silverware dr0ught.... .
Last 5 matches of Man. Utd :
Wolves 1-0 Manchester United
Manchester United 2-1 Manchester City
Wigan Athletic 0-4 Manchester United
Chelsea 2-1 Manchester United
Liverpool 3-1 Manchester United

Loses of Manchester United:

Well.. against Wolves.. in the first five minutes of the match....
Man. Utd perhaps been touted as the better side between these two sides...
well.. a brace from Nani's effort proved that... After that.. is all about Wolves.. ten minutes in.. quick corner from Wolves as Man. Utd defenders lack of concentration during that time and Wolves took advantage from it..and the outcome is a goal for Wolves.. fine header by Elokobi as he seized the pace of the ball to beat V. Der Sar  towards the right side corner of the net.. 1-1....
Several ocassions later, Wolves were awarded a free kick...
For your information, set pieces are very important elements for any small teams to gain a goal against a big guns such as Man. Utd... So..
they do not take it lightly... Due to this free kick... Wolves are scoring again...
but this time through the header of Kevin Doyle with the help of Elokobi who his physical presence
in the box allowed Kevin Doyle to get a clean header... 2-1.....
Well... Man. Utd want to turn things around.. they have their beliefs in order to do so.. as they have done it against Blackpool... Coming behind from 2-0 down to win the match 3-2 in a thrilling encounter....
but.. against Wolves.. they cannot repeat it again.... And from 29 games unbeaten.. finally comes to an end...
..



Against Chelsea... well.. what a dramatic match it was.. many controversial decisions,fantastic atmosphere all around the stadium,hard-working and high passionate performance by all the players throughout the match.. and also the match that cause the title race even wide open again as the United lead points cuts to four points.. somewhat a great news for all the Arsenal's family...
