Barcelona are pushing Manchester United to accept a swap proposal for Donny van de Beek.
The Holland midfielder has been offered to Barca by agents as an alternative to Gini Wijnaldum, who snubbed the Blaugrana for PSG when leaving Liverpool this summer.
Barca do not have the finances to cough up a fee for Van de Beek and instead are proposing a swap with United.
Mundo Deportivo says France defender Samuel Umtiti has been offered to United.
Knowing they're attempting to close a deal for Real Madrid stopper Raphael Varane, Barca have raised the prospect with United of taking Umtiti as an alternative.
