The Wales international is currently the planet’s most expensive footballer following his £86m switch from Spurs to Los Blancos in 2013, but his time at the Bernabeu has come under scrutiny recently.
Bale was booed by some Real supports during the weekend’s 3-0 win over Espanyol – in which he netted a stunning free-kick – with his failure to pass to Cristiano Ronaldo when in a good position, which he missed from, a source of frustration.
United have long been linked with the flying wide-man, and amid the uncertainty, a £117m raid has been kick started, which the European champions are ready to accept.
The decision will ultimately, however, be down to Bale as to whether he wants to leave Real.
The ex-Tottenham man has enjoyed a fine 18-months in Spain, helping his side to claim their tenth European Cup by netting a vital goal in the final against Atletico Madrid.
