Palace have completed the signing of German winger Marco Reich on an 18 month contract.
Reich has been with Palace since arriving at the club as a free agent in September. His short-term contract ran out this month, but the midfielder has now committed his future to the Eagles.
Speaking to the official Palace website, the 28-year-old said: "I've been here for four months and Palace have given me a great chance on trial.
"Since day one I've wanted to stay here because Palace are a really ambitious club and I'm sure we can reach our target of getting to the Premiership."
