Horsten will join Roda on a free transfer at the end of the season.
“Eelco is a young defender with a lot of potential. He’s both physically and mentally quite strong. The competition at PSV is very stiff and he has more chances to get first team action at Roda,” said Roda’s technical director Martin van Geel on the official Roda website.
The 20-year-old has signed a two-year contract at Roda.
