Robert Lewandowski has cut ties with Chinese technology company Huawei amid unconfirmed rumours they are helping Russia defended themselves against cyber attacks.
Huawei have firmly denied claims of involvement with Russia and there is no evidence to support the claims.
But Lewandowski has taken a stand and cut ties with the company in a move that will cost him around €5m (£4.14m) having recently signed a three-year deal with the technology giants.
