AS Roma has today activated a clause to buy defender Antonio Rudiger from VfB Stuttgart 1893 e.V. on a permanent basis for a fee of €9 million.

The agreement also includes an additional payment of €0.5m depending on whether Rudiger triggers specific sporting clauses.

Rudiger’s contract expires on 30 June 2020.

The Germany international initially joined the club on loan last summer, making his Serie A debut against Frosinone in September 2015. He went on to make 30 league appearances for the Giallorossi, scoring two goals.

The 23-year-old is currently training with the Germany squad ahead of the forthcoming European Championship in France.
