Jan Koopmeiners, 81, played an important role in the football careers of his grandsons Teun and Peer Koopmeiners, according to the account. For years, he served as their private driver. Teun, 28, is set to play for Juventus against Peer, 26, and AZ in Alkmaar on Thursday, with their grandfather expected to be in the stands.

The account described Jan Koopmeiners’ support for his grandsons and said he considered the day Teun obtained his driving licence the saddest day of his involvement as their driver.
