Donny van de Beek is not yet participating at Ajax on Saturday in the home match against sc Heerenveen. Trainer Erik ten Hag hopes that the midfielder can play on Tuesday in the Champions League match against OSC Lille.

Van de Beek has resumed training after his hamstring injury, but has not yet trained with the group.

"We work with Donny from day to day, but we are careful," Ten Hag said Friday. "We don't want him to repeat with his injury. He won't be there on Saturday, but we're working towards Tuesday."

Dusan Tadic counts as a question mark for the Frisian duel. Unlike Van de Beek, the Serbian did train with the group, but still has minor complaints. "It is quite possible that we will start without him," says Ten Hag.

The match between Ajax and SC Heerenveen starts on Saturday at 6.30 p.m.
