Everton boss Roberto Martinez has confirmed his side ‘concede too many goals’ following their 1-0 defeat to West Brom at Goodison Park.
The Toffees had 34 shots, but couldn't find the back of the net as the Baggies sealed three points thanks to Salomon Rondon's 15th-minute close-range goal.
It was Everton's sixth home defeat of the campaign and Martinez said after the clash: "It is the truth. We have conceded too many goals.
"Today that little bit of luck was not in our favour but we have to change that.
"The home form is where we were looking forward to get a fortress, to get good results even when you are not playing well, and it hasn't been the case.
"We have been so strong away from home - that is where you get tested. We have got the best away record we have had for a long time."
He added: "There is that element that sometimes a dominant performance doesn't give you a good result and that was the story.
"We knew exactly what we were going to face. West Brom were organised, they were going to take 30 seconds over every dead-ball.
"They had one shot on target and we had over 30 attempts and hit the post and the crossbar. I thought the dominance deserved a better result."
