Potter fielded two separate XIs in each half but neither were able to force a goal in a match played behind closed doors at the American Express Elite Football Performance Centre.
Potter, who guided Albion to ninth in the Premier League last season, said“It was a good exercise for us. It was a case of getting players time on the pitch at this stage of pre-season and building relationships and we did that
“We had a couple of mixed teams out there, but I thought the attitude of all the players was fantastic.
New arrival Julio Enciso played the first 45 minutes, and Deniz Undav, the striker who spent last season on loan with Union also featured.
Potter added: “Julio and Deniz looked sharp, they both had a positive impact on the game.
"They have only been with their new team-mates for a few training sessions.”
