Schalke have signed Brazilian midfielder Danilo Fernando Avelar on loan until the end of the season.
The 21-year-old makes the move from Ukrainian outfit Karpaty Lviv and Schalke have an option to make the move permanent in the summer.
"It is a big honour to become a Schalke player and I am delighted to be able to play alongside so many fantastic players," he told Westdeutsche Allgemeine Zeitung newspaper.
"I am going to give my best. I need to settle fast and I need to show everyone what I am capable of."
Erik Jendrisek is looking for a fresh start at Freiburg, though, after sealing his departure from Schalke.
The Slovakia striker had expressed his desire to leave Schalke having made just three substitute appearances after signing on a free transfer from Kaiserslautern in the summer.
Second division Arminia Bielefeld had been linked with a loan move for Jendrisek while Greek side Panathinaikos were also said to be interested.
But the 24-year-old preferred to stay in the Bundesliga and has signed with Freiburg until June 2014 for a fee of around £750,000.
Jendrisek made his debut in Saturday's 1-1 draw against Nurnburg and coach Robin Dutt believes he will be a valuable asset.

"Erik Jendrisek is a fast player with a goal-scoring mentality, he will strengthen our squad and I really feel he will also be a boost to our ranks in terms of personality," he told Kicker-Sportmagazin. "We are happy to have signed him from Schalke."
Meanwhile, Schalke have signed teenager Julian Draxler on a professional contract until June 2014.
The 17-year-old midfielder was handed his debut as a substitute in last week's 1-0 defeat by Hamburg to become Schalke's youngest Bundesliga debutant.
Coach Felix Magath then gave the German Under-19 international, who has been with the club since he was eight, his first start in Saturday's 1-0 win at Hannover.
"He has all the skills to develop into a very good player," Magath told Hamburger Abendblatt newspaper.
"He is already doing many things just right on the pitch. Looking at his age, the maturity he is showing is simply astonishing."
