Ghana international Abdul Rahman Baba played for Schalke on Thursday night as they drew 3-3 with Southampton in a pre-season game.
The Ghanaian was excellent at left-back as the Gelsinkirchen club shared parity with the EPL side at the Kunshan Stadium in China.
Both clubs are in the far east preparing for the coming season and they used the game to examine the rough edges in their team.
Schalke will play their next friendly game on Tuesday July 11 against Hebei China Fortune.
