Big Sam was appointed West Ham manager in June 2011 with the task of returning the Hammers back to the Premier League after their relegation.
He fulfilled that task after beating Blackpool in the Championship Play-off Final at Wembley Stadium, before securing safety in the 2012/13 Premier League season with two matches to spare.
After two comfortable seasons in the top-flight, Allardyce left West Ham following the expiration of his contract.
Allardyce, who also had spells at Bolton, Newcastle, Blackburn, Sunderland, England, Crystal Palace, Everton, West Brom and Leeds, will be in Studio One at the Etihad on Saturday to analyse our clash with the Hammers.
