West Ham United boss Sam Allardyce believes Rafa Benitez was onto a loser taking the Chelsea job.
Allardyce, who takes West Ham to Stamford Bridge tomorrow, has never seen eye-to-eye with Benitez since the Spaniard's time at Liverpool.
But Big Sam said: "I think Chelsea have suffered because the fans have not been fully supportive. That's nothing to do with Rafa, he's doing his job.
"But it shows the effect it can have on the team when you have a volatile fanbase that can turn the other way."
