Real Madrid have reached an "agreement in principle" to pay Monaco up to €180m (£161m) for Kylian Mbappé, according to reports in the Spanish capital.

The transfer, should it be completed, would become a world record, eclipsing the £89m fee paid by Manchester United for Paul Pogba last summer.

Madrid have agreed to pay €160m plus another €20m in performance-related bonuses for the 18-year-old striker, Axar.az reports citing on Marca, though Monaco say that as yet they have not agreed on a sale.
