Manchester United fans all over the world have been calling for Shinji Kagawa to start for the Red Devils.

However, David Moyes has been right not play the Japanese playmaker.

Kagawa can only really play two positions at the club, left attacking midfielder and right behind the striker. At any other position he is ineffective.

He can not play a deep central midfield role as he is too weak to play there and will be to easily bumped off the ball by players like Victor Wanyama or Yaya Toure, and Kagawa tends to play his best football higher up the pitch as dropping deep to receive the ball is not a part of his game.

The bad thing for Kagawa is that he simply can not find any opportunity to play, and this has been wholeheartedly justified.

There has been a lot of criticism over Manchester United's wing play, however, is Kagawa the answer to United's woes?

No, because as a winger you have to be explosive going forward and be able to do the work defensively.

While Kagawa is exciting going forward he is woeful on the defensive side. He does not have the strength or defensive capabilities to stop opposing wingers.

Alongside an ageing Patrice Evra an already problematic left side of United's defence would become only more problematic. Kagawa simply can not do the work that is required as a left midfielder.

So why does he not play right behind the striker? Well, the answer is Wayne Rooney.

The renaissance of Rooney at Manchester United has severely cut down on the opportunities that Kagawa gets at the club. His form at the beginning of the season has been undeniably brilliant, and there is no spot in the Manchester United starting line up when Rooney is performing as well as he is.

And to add on to Kagawa's problems there is Adnan Januzaj.

The 18-year-old has been the brightest star in Moyes' side. His neat play and creativity has wowed Manchester United supporters and the manager alike, as he was rewarded with a new five-year contract.

So tell me Manchester United fans, would you rather play Januzaj and Rooney, or Kagawa?

Now, please do not get me wrong. I am not saying that Kagawa is a bad player, because he is not. He is absolutely world class.

But he does not fit into the style of play Manchester United plays at the current time.

Other players like Januzaj and Rooney are a better fit to the line up than Kagawa is, and Moyes understands that.

He has been absolutely correct in leaving the Japanese star out of his line up.
