West Ham United boss Sam Allardyce expects a tough challenge against struggling Leicester City.
West Ham, who have lost just once in 10 matches, will see their ambitions tested with Christmas fixtures against Chelsea and Arsenal, so Allardyce knows the importance of a positive result on Saturday.
"Leicester are a hard team to break down, they work very hard for each other, despite their run of games without a win, they haven't been turned over by anyone, it's only ever by the odd goal, so there are a lot of dangers in Nigel's teams that we need to be well aware of," he said.
