Everton boss Roberto Martinez will bring in fresh faces next month to provide cover for injured duo Arouna Kone and Darron Gibson.
Kone's serious knee problem could rule him out for the rest of the season, while Gibson's similar injury is expected to sideline him for a lengthy spell.
The absence of the pair has shortened Martinez's options ahead of a hectic schedule and he hopes to bring in new recruits.
"We are going to use the window in January to try to help the team because we lost two players for the long term," said the Spaniard.
"Arouna and Darron are two very important players for us so we will try to see if we can identify one or two players that can help the group.
"We have been working hard to identify who can help the group and that is what we are looking for in January."
Kone has begun his rehabilitation, but Martinez does not expect his signing from Wigan to return before the summer.
"Arouna started the first part of his recovery and it is going to be long-term, as expected," he said.
"I don't think we are going to see Arouna this season.
"If we can get him back for the final two months he will have done really well.
"There was a big chunk of cartilage that had to be repaired in his knee.
"In the same manner we are hoping we can see Darron Gibson before the season ends but clearly it is a long-term injury as well."
