Chelsea failed to score for only the second time in a Premier League match this season in Sunday’s 0-0 draw with Everton.
And coach Maurizio Sarri says he is concerned with the number of chances his manne created as they missed opportunities in the Stamford Bridge stalemate.
The Italian says: “To be honest, I didn’t like the first 25 minutes very much. Like against Crystal Palace [last week], we started the game moving the ball very slowly, so it was impossible for us to be dangerous and easy for Everton to defend.
“We created few goal opportunities in relation to how much we played. So in this moment maybe it’s a little problem. We have to be careful because in the last three matches you are right.”
