Jose Mourinho held a dressing room inquest after Chelsea's shock Champions League defeat to Basel.
Mourinho demanded immediate improvements from his shell-shocked Chelsea players during a meeting with the entire squad at their Cobham training centre, says the Daily Mail.
As is customary, he spoke to a number of players about their performance, but there is no sign of tension, just acceptance that the form must change after a tricky start to Mourinho's second spell at Chelsea.
Some of the points raised by Mourinho at Cobham have been interpreted as 'constructive' and 'positive', but a number of players were left in no doubt their places are under threat.
