Their back four might change, but it is solid

Against Everton, Petr Cech was installed in goal and Thibaut Courtois dropped to the bench.

It proved to be a masterstroke by Mourinho and Cech kept the Blues in the game.

Likewise changing up John Terry’s partner at the back has not negatively affected the side – in fact Kurt Zouma has come on leaps and bounds.

The Blues are strong at the back and keeping the opposition out makes it all the more likely they will nick the three points with a late goal if things come down to that.
