Clubless Wales international winger John Oster played a full 90 minutes for Derby County on Wednesday.

The 29-year-old trialist, who has been without a club since leaving Reading at the end of the 2007-08 campaign, was involved in a 1-1 draw away to Oldham.

Tito Villa scored the Rams' goal after 15 minutes with Oldham equalising seven minutes later.

Polish midfielder Presmislav Kazmeerjak made his Derby debut but was replaced by Robbie Savage in the second half.

Derby travel to Mansfield on Saturday for their next pre-season friendly.
