With Marcos Rojo Starting at Left Back and Tyler Blackett's starting spot set in stone. Does this affect Luke Shaw's development?

On the weekend against Queens Park Rangers, Marcos Rojo has started at left back for Manchester United.  Making his Old Trafford debut alongside Tyler Blackett who had impressed this season so far.  Luke Shaw, who was brought to Manchester United on a £30 million move from Southampton was left watching on the bench, still awaiting his Manchester Unitd debut.

Luke Shaw without a doubt is a young talent after having an impressive season with Southampton.  Holding United to a one all draw in Southampton the last day of the season.  Then comes the surprise of Marcos Rojo, who had an impressive World Cup scoring a goal in the group stage against Nigeria and reaching the Final before eventually losing to Germany 1-0 on a Mario Gotze goal in the dying minutes.  

Most United fans would have predicted that Marcos Rojo would be playing centrally alongside Phil Jones.  With Jones injured, it was very possible that Van Gaal would fit Rojo in right centre back, but Louis Van Gaal pulled a bold move by starting Jonny Evans who had been struggling against MK Dons and Burley.  Everyone would have thought Luke Shaw would be starting, but Van Gaal said publicly in his pre-match press conference before the match against Queens Park Rangers that Luke Shaw was not fit enough to play an entire match.  

Marcos Rojo had a a good match, but was caught out on the counter attack which as a result also got David De Gea out of position, only to be saved by a sliding save from Jonny Evans that prevented United from conceding.  Luke Shaw is just 19 years of age and have gone up the ranks quickly with Southampton, but with Louis Van Gaal in charge at Manchester United, opportunities are not being given but earned.  

Shaw was consequently played in the Under 21 Barclays Premier League fixture.  Providing an assist to Adnan Januzaj who claimed his hat trick in a 4-0 win against Sunderland a day after United's match against Queens Park Rangers.  

You could argue that Luke Shaw as unfortunate that he picked up an injury during pre-season which resulted in Tyler Blackett having an opportunity to play at centre back and moving Marcos Rojo to left back, occupying Shaw's position.  However, Louis Van Gaal's recent comments have proven that nobody is safe no matter the price tag that is on the player.

Luke Shaw is still young and has things to learn for his development.  Marcos Rojo has earn his place through his impressive showing in the World Cup.  Through hard work and dedication, it is possible that Shaw could be a regular starter for Manchester United in 2-3 years time.

With the FA Cup still up for grabs,  Luke Shaw will certainly will get playing time with academy product Adnan Januzaj and James Wilson.  Hopefully this group could gel well and be the future of Manchester United in 4-5 years time.  Youth development is not a sprint, and breaking into the first team rotation for Manchester United is not an easy task.  Fitness is key for a Manchester United player and if Shaw manages to up his fitness, it is very likely that he will have more opportunities to start in the Barclays Premier League.
