Long are days gone where Jose Mourinho's sides would turn over their opponents with power and efficiency. That concept no longer seems to work with the game evolving and teams being able to adapt.
Last night saw Mourinho's side crash to a 2-1 shock defeat to a very good Basel side, who kept going despite conceding a goal on the stroke of half time. It was the first time the Swiss side had won on English soil and it showed how much it meant to them.
It was Chelsea's first home defeat in the Champions League group stage in almost a decade and the worrying signs are that the Blues haven't now won in four consecutive games, with a draw at Manchester United, and losses to Bayern Munich in the Supercup final and Everton.
Mourinho certainly took the responsibility for the loss but at the same time questioned the character and maturity of his players despite describing them as "young eggs who need nurturing".
The players on display were far from inexperienced however, with the exception of Marco van Ginkel.
Mourinho said: "Of course [it hurts] but I think the team probably is not a team with such maturity and personality to face the difficult moments of the game".
"After Everton we played amazingly and they scored in the last second of the half and, after that, you could feel the team was struggling despite dominating the game. This was a bit the same".
Mourinho will have to go back to the drawing board and analyse where the problems lie, and it will be imperative for Chelsea to bounce back with a win on Saturday's home game against Fulham as they cannot afford anymore blips if they are to win the title.
