Everton winger Kevin Mirallas blames himself for back-to-back 0-0 draws.
Everton have dropped points against Tottenham and Crystal Palace in the past two games.
Mirallas said: "I have become an important part of the team and, in the last two games, we have had bad results because I played less well.
"This had on impact on the whole team.
"I have to stop this lack of consistency, even if opponents are now marking me more.
"The whole team plays through me so that I can make the difference and provide good passes to Romelu (Lukaku)."
