Chelsea manager Jose Mourinho believes his side are making improvements at the back following back-to-back clean sheets in all competitions.
His side have struggled at the start of this season, but a win against Aston Villa in the Premier League last weekend meant they climbed to 12th in the table, and that was followed by a creditable draw in the Champions League in midweek.
“I try the best decisions for the team and analyse opponents and what the team can be and try to reduce that unpredictability of every match but you are right that this is not about defenders.
“It is about the team as a team and they defended well in both matches.”
Recently, selection of some of his more well-known players has been in the spotlight, and Mourinho was asked about whether Eden Hazard would play on Saturday, after being omitted from the starting XI against Aston Villa, and said he didn't know if he would play in Saturday's fixture at the Boleyn Ground.
The Chelsea boss added: "He played the last match for 90 minutes and was part of the compact team that kept that clean sheet.
“You have lots of people giving opinions and speaking about him. I’m happy with his contribution against Dinamo and that’s it.”
If Hazard is left out of the line-up again, then it will inevitably give newspapers a story to write about and something to ask questions about in the future.
Three players that certainly won't be lining up against West Ham are Thibaut Courtois, with the goalkeeper continuing his recovery from a knee injury, Spanish forward Pedro and long-serving defender Branislav Ivanovic.
