I wouldnt go as far as the poster has suggested,Because at times he has been a brilliant player for us, but think carefully about the situation, was Darren Fletcher better than Paul Pogba is now when he was introduced to first team action ,no he was not.
Everybody knows the amount of time Darren Fletcher was given to improve as a player and the amount of first team opportunities,So therefore if he was given the chance why shouldnt Pogba and Morrison.
Then would they improve to a better level than Darren Fletcher or Darren Gibson for that matter are currently at? Its just my opinion because anything can go wrong in a young players career,but i believe they would exceed those players i just mentioned .
