The Blues continued a run of extremely poor results since the most recent international break.
Post-game, he told reporters: “I think it's about to improve. We were talking after nearly four or five months, or 16 games, it's about to assess. We were not able today with all of the chances we had.
“We need to score if we want to win the game and we want to be in a different position in the table. It is not only to play, the team played well, dominated the game against a very difficult team like Everton.
“When you assess Everton, we deserve full credit because I think we were much better than them but in the end you need to score because if not, you build the confidence of the opponent and it is impossible to go 96 minutes without making a mistake."
