Chelsea are suffering travel sickness having incurred losses to Paris Saint Germain at the Parc des Princes, Crystal Palace at Selhurst Park, Aston Villa at Villa Park and Manchester City at the Etihad Stadium.
For a club challenging on two fronts - the Premier League and the Champions League - during the business-end of the season, that will be a cause for concern as it is imperative that when title challenges reach their climax, a team has both momentum and confidence; like Liverpool or PSG.
Commenting on the Stamford Bridge side's 3-1 defeat in France on Wednesday evening, Jamie Redknapp said on Sky Sports that manager Jose Mourinho will be "disappointed" as the performance was very "un-Chelsea".
He continued: "That’s four of their last six away games they’ve lost now - something is wrong there."
On the club's flaws, Redknapp highlighted the dearth of quality options in the striking role, claiming that Andre Schurrle was perhaps used unfairly as the German will have been so used to playing out wide all season, while Fernando Torres' confidence is shot.
Schurrle, Redknapp said, "didn't know where to run" and the substitution of Torres "just didn't work".
He concluded: "[Mourinho] has to take responsibility. His team has not reacted to what he wants and they’re too easy to beat. It’s nothing like what you expect from Chelsea."
