Newcastle's £53million move for Gareth Bale could set off a remarkable chain of transfers across Europe's biggest leagues.
Reports in Spain on Tuesday claim that Newcastle, armed with cash from their proposed £300m Saudi Arabian takeover, have set their sets on the Welshman.
And, according to Sport, it could set off a domino effect that would involve two other big-money transfers.
They claim that Real Madrid would seek to go after Bayern Munich winger Kingsley Coman as a potential replacement.
Coman's departure from the Allianz Arena would then be quickly filled by Leroy Sane.
