West Ham United manager Sam Allardyce has insisted that stranger things would have happened this season than if his side beat Liverpool, and said that the Hammers have a chance on Sunday at Upton Park.

Allardyce said that his players have taken confidence from their run of form in 2014 and are looking to emulate Crystal Palace and Sunderland, who have beaten Chelsea and Manchester City respectively.

"Since the turn of the year, our change of form and results has got better and better and now we're in the best run we've had since we've been back in the Premier League," Sky Sports News quotes Allardyce as saying.

"We've got to take that confidence into Sunday's game and hopefully we can produce one of those performances that has happened many, many times in the Premier League this year.

"Just the other week Crystal Palace beat Chelsea, and Manchester City lost to Sunderland, things like that can happen."

The game kicks off at 4pm on Sunday.
