#4. David De Gea
A man who was hailed by many as the best goalkeeper in the world during the previous campaign, Spanish International, David De Gea has failed to reproduce his extraordinary performances between the sticks at the Old Trafford this season.
The former Atletico Madrid goalkeeper has been an ordinary shadow of himself since the beginning of the term, having already conceded a whopping 29 goals in 17 Premier League appearances for the Manchester outfit so far as well as letting in 4 goals in the UEFA Champions League, to sum up, how miserable his performances have been.
There is no denying De Gea belongs among the most talented guardians in Europe at the moment, but he needs to work really hard and improve his performances at goal to preserve his reputation and also help Manchester United in the revival mission this season.
