Chelsea captain John Terry admits manager Jose Mourinho likes his players to "get in the faces" of their opponents early in games.
"When you go away to the likes of Everton they are going to try and do exactly the same to you.
"We have to fight for it and work hard for it."
Terry added: "When you are playing against a very good side, like Man United for instance, if you give them time to play there are so many world-class players in their team that they will find a pass to hurt you or create something from nothing.
"But if you get in amongst them and get in their faces a little bit and put them under pressure they make mistakes."
