#4 Ryan Giggs
The only managerial job that Ryan Giggs has taken up is the role of the assistant manager under Louis van Gaal at Manchester United. But he has the know how of football and how it works from top to bottom.
He is another one of those people who has drawn links to every club once their manager gets sacked. Be it Middlesbrough last season or Swansea City on two occasions, Giggs landed neither of the jobs and still works as an expert. He has previously made it clear that he wants to return to management and a club like West Ham would be testing for someone like him. He will have a good side at his disposal and very few hate him.
And the respect he commands can play a vital role in making him an eventual success at the London based side.
