The former Liverpool star will rejoin his team-mates after going through an intense recovery period following knee surgery two months ago
The Dutchman has been out of action for two months after going under the knife in January, and went through a number of individual sessions in a bid to regain fitness.
And he has now resumed regular training with the rest of his team-mates ahead of the final stage of the Eredivisie season.
"I am a happy man. After many individual sessions, I finally returned to the group," he wrote on his Twitter account.
With seven matches left of the campaign, Frank de Boer's side are currently top of the league, with one point separating them and Feyenoord, who sit third.
The Amsterdam outfit face NEC on Sunday and Heracles the following week.
