3. Rafael
Many thought Rafael would be the ideal replacement for Gary Neville when he joined United in 2008. Unfortunately, the Brazilians career hasn’t really taken off during his time at Old Trafford. The full back seems to be fine going forward but he has always seemed a liability at the back. There always seems to be a mistake on the horizon when Rafael is playing. The 24 year old is no Gary Neville and Van Gaal appears to know this, not selecting the defender in any of United’s league games so far this season.
