#5 Sam Allardyce

This one sounds pretty crazy as of course, ‘Big Sam’ is rumoured to be in retirement following his shock resignation from Crystal Palace at the end of last season. That followed his incredibly controversial and short run as England manager, a run that ended after just one game following a very questionable interview with undercover journalists.
And to add to that, Allardyce has been at West Ham before, and his run ended acrimoniously – he left by mutual consent after some fans turned on him due to his supposedly unattractive style of football, even labelling him ‘Big Sham’.
The bottom line, though? Regardless of how you feel about his style of football, Big Sam is a fantastic manager who’s proven himself time and time again, particularly at clubs who are struggling for success.
You only have to look at what he did at Sunderland in 2015/16 – he saved them after a horrific start left them with just three points from their first eight games. And at Crystal Palace last season he performed another miracle, guiding them to a 14th place finish despite losing eight of their first thirteen league games.
Wins over Chelsea and Arsenal – two of West Ham’s London rivals – were the highlights of Sam’s time at Selhurst Park. And while appointing him at West Ham again probably wouldn’t be a popular decision with the Hammers fans, if the club find themselves in trouble again and have to fire Bilic, then there’s probably no better free agent – assuming he’d be willing to do the job – out there to save the club.
