Kane has scored 23 goals in all competitions this season and Allardyce said: “It shows you that, in this game, you never can tell.
“His previous education, though, when he went out on loan a number of times, has helped him no end and paid handsome dividends.”
The Hammers boss thankfully has Winston Reid, James Collins and Matt Jarvis back in the squad and said: “We know what a big derby this is. We managed to beat them three times last season — twice on their own patch — but then had the disappointment of losing to them with a last-minute goal in the opening game this season.
“Players such as Ryan Mason and Nabil Bentaleb have developed so well this season, they are keeping some of the big-money signings out of their midfield.”
