West Ham United boss Sam Allardyce believes Tottenham manager Andre Villas-Boas will have revenge on his mind today against Chelsea.

Big Sam was harshly shown the door by Newcastle chairman Mike Ashley in January 2008 despite a reasonable start.

He said: "If you feel you've been unfairly dismissed then you want to be able to show them what they are missing.

"You say 'Look lads, these guys sacked me so do us a favour and get us a win'."
