Matt Jarvis knows West Ham face a critical period over the next month

West Ham winger Matt Jarvis says the club are preparing for a tough spell over the next month as they face their most challenging run of fixtures yet.

Allardyce

Jarvis has been impressed by the approach of Allardyce since arriving from Wolves in the summer and says the manager reminds him of his old boss Mick McCarthy. He said: "There are similarities between Big Sam and Mick McCarthy, who was my manager at Wolves. "They both have an aura and presence about them. And if you do something wrong you know about it! "Sam has put his own mix on things and a lot of his ideas are very heavy on stats. "We have meetings about the opposition but he looks at our stats on set-pieces and everything else. "It works for him and everyone is buying into it. It's the first time I have had this approach. He really likes it and I think it shows in what we do, there's no place to hide."
