Leighton Baines is still not over his ankle problems and John Stones has been sidelined with a hamstring injury but Everton boss Roberto Martinez assures them they have a part to play in what remains of the campaign.
With only two goals conceded and five wins registered over the last six matches, Everton have fared quite well without the pair, who are looking to be part of England's Euro 2016 squad.
"Those two are vital for our future plans and for us to be successful from now until the end of the season, they are going to be a big part of that," the Spaniard said.
"With Leighton, we have a little bit of a worry - he has been carrying a little bit of a niggle in his ankle and we have to make sure that gets right.
"Since the surgery, it has been giving him a little bit of soreness and managing that pain at times has been a little bit difficult.
"When he came on against Aston Villa (on Tuesday) he felt at times he had to play through the pain, and we have to make sure we solve that, because it is very unfair on Leighton.
"We will see a specialist, but it shouldn't stop him from training.
"John is still a very young man who has already played the biggest amount of minutes he ever has in his professional career.
"So it's important he is fully refreshed and ready for the final push in the campaign.
"He is a very important footballer for us."
