Maurizio Sarri was left bewildered by the second-half slump that condemned Chelsea to a costly 2-0 loss at Everton on Sunday.
The visitors started brightly at Goodison Park and created several chances to open the scoring, in what Blues boss Sarri labelled his side's best 45 minutes of the season.
However, the inability to convert that dominance into goals came back to haunt the Champions League hopefuls as Richarlison and Gylfi Sigurdsson struck after half-time for a much-improved Everton.
The result dented Chelsea's chances of breaking back into the top four, with three points separating them and Arsenal heading into the final eight games of the campaign.
"It is difficult for the players to explain to me the change. It is very difficult for me to explain to you the change. Probably it is a mental block I think".
Sarri denied the players were not responding to his motivational methods.
