Chelsea fullbacks Jose Bosingwa and Ashley Cole admits Guus Hiddink has changed the style of play that former boss Luiz Felipe Scolari employed.
"It is different with the new coach, we are not conceding goals and have a slightly different mentality," Bosingwa told chelseafc.com. "He tries to change a few things, which is normal.
"I am a little more defensive, which is always the first part of my job, to make sure we do not concede, but am still able to go forward and help the attacks, so it has not changed too much."
Cole, who has shown some of his best form in a Chelsea shirt this season, added: "We have to stay back a bit more now and defend as a unit, and maybe that could be the change that could change our season."
