Paul Pogba has thrown his Manchester United future in doubt as he has reportedly turned down a new deal at the Old Trafford club.

This has inadvertently kept Real Madrid on red alert over the French midfielder.

According to the Sun, Pogba is looking for a new challenge after nearly three years at Old Trafford – and Real are said to be preparing a £125m bid.

Paul Pogba recently fuelled speculation over of his Manchester United exit when he said playing for Real Madrid under returning manager Zinedine Zidane would be a “dream for anyone”.
