#5 Diego Simeone

This may seem like an outside bet at this stage, and it probably is, but there are a number of reasons why United should consider Simeone as their new manager. What he has achieved at Atletico Madrid is nothing short of extraordinary.
In terms of stature, and financially, they are a million miles behind Real Madrid and Barcelona, but somehow, under Simeone, the clubs are in a very similar position on the pitch. He has taken them to two Champions League finals and won the title in the 2013/14 season.
However, there is a feeling that Simeone has taken Atletico as far as he can, and there isn’t much more he can achieve there. He may feel that his job is done there, so he may be looking for a new challenge, and that is something he will get at United.
He has made Atletico one of the top defensive sides in Europe, and that is an area where United really need improvement. He might just be the perfect man for the top job at Old Trafford.
