Tim Howard saved a first-half penalty to ensure the score remains goalless at half time between Everton and Aston Villa.
The hosts have created the better chances so far, but have found the Toffees goalkeeper in good form.
After an even start, Villa were given a great opportunity to take the lead when Seamus Coleman tripped Christian Benteke in the box and they were awarded a penalty.
The Belgian picked himself up and struck a competent penalty towards the corner, but was denied by Tim Howard.
Everton's goalkeeper had to be in good form again shortly afterwards, first denying Benteke and then diving at the feet of Andreas Weimann in a one-on-one.
The away side then created their first real chance when Romelu Lukaku met Coleman's cross, but Brad Guzan reacted well to turn his header wide.
There were few chances after that and Villa will be wondering how they are not ahead after the first 45 minutes.
