West Ham will go for their fifth straight league win when they take on Liverpool on Sunday - so, can anyone stop the high-flying Hammers?
"There's no secret to why West Ham are doing so well at the moment," said BBC football expert and former Liverpool defender Mark Lawrenson. "It's down to hard work, good organisation at the back and the fact they are taking their chances.
"This should be a really good game, especially because Liverpool have ground to make up on the teams above them - it's a must-win for the Reds."
Lawro is making predictions for all 380 Premier League matches this season, against a variety of guests.
