The 24-year-old Switzerland international will stay at Everton until the end of the season.
“I am delighted to be an Everton player for the remainder of the season,” he told the club’s official website. “I can’t wait to get stuck in and play for Everton.
“Hopefully I can get some first team football in during my time here. I am here with high hopes and hopefully I can fulfil them.
“I have spoken to David Moyes and he hopes to give me opportunities here. Hopefully I can grab that opportunity and stay in the team.
“Everton’s form over the last few weeks has been better and they are getting stronger.”
