Chelsea boss Roberto di Matteo is ready to abandon their attacking ways to shake off their form slump.
Chelsea have operated an attack-minded 4-2-3-1 formation under Di Matteo but that looks set to be reassessed after defeat to West Bromwich Albion.
Di Matteo said: "This season we are playing a little bit different but we might have to go back (to a previous formation) to be able to win games, and make sure first and foremost we don't concede.
"Maybe it is the time where we might have to change a little bit in terms of our selection and the way we play.
"For some reasons, November for our club is a bad month and it seems the same again this year.
"We are disappointed and maybe it is time to look at things, maybe change it a bit and get a win.
"We will look at the set-up of the team and maybe sacrifice a bit the attacking options to go a little bit more defensive."
