Rio Ferdinand says Cristiano Ronaldo will be 'very disappointed' if he isn't still performing at the highest level when he reaches the age of 40.
The Portuguese star, 36, is poised to play the first action of his second spell at Manchester United and could feature when they take on Newcastle on Saturday afternoon.
And former United defender Ferdinand expects him to emulate the likes of Ryan Giggs and Teddy Sheringham by playing well into his next decade.
'If Ronaldo doesn't get to 40 and isn't playing at the top level he'll be very disappointed,' Ferdinand said in conversation with heavyweight champion Anthony Joshua for William Hill.
