Thomas Hitzlsperger's stay at Everton has been extended until the end of the season.
The former German international joined the Blues on a free transfer in September and has subsequently made seven appearances.
His short term deal was originally set to end in January but the midfielder will now remain a part of David Moyes squad until the summer.
Moyes said: "Thomas is going to stay until the end of the season. He wants to play, like everybody else.
"We've needed him and we will continue to need him with the games we have got in the second half of the season.
"I was thinking about letting Ross (Barkley) go out on loan and Thomas' experience allowed me to do that. I just felt that keeping him was important."
