3. Jose Mourinho
This might be a controversial figure in the Premier League but Mourinho does make his team mentally strong, alright maybe this season did not go as expected for the Portuguese but the former Chelsea, Inter Milan and Real Madrid manager has a history of making tough teams and more importantly, winning stuff as well.
The Chelsea man is without a job now and even though Arsenal fans may loathe him, he can get the job done and make Arsenal at least, will win a Premier League crown quickly, even though he could get sacked in a couple of years, is that a risk worth taking to win the big prize?
