Chris Richards signed a five-year deal with Crystal Palace for an initial 8 million pounds and an additional 2.5 million pounds.
He spent last season on a loan at Hoffenheim.
The arrival of Matthijs de Ligt has pushed him further down the list of available slots.
Richards is excited to be a part of the historic club.
It will be cool to spend some time on the field with them because I grew up watching them in the premier league.
Young players who have a lot of fight are included. He said that Palace is a club that is always fighting.
Before his permanent deal was made in January, Richards was on loan from FC Dallas for a short time.
The defender, who can play in a number of positions, has made at least one first-team appearance in each of the past three seasons.
He is the fourth new signing of the summer for the Eagles.
