United legend Cole believes that the Sancho deal could turn out to be a bargain for the London club.
"Manchester United paid over £70 million for Jadon three years ago, so it’s a lot of money lost, isn’t it?" Cole remarked in an interview with Betfred.
"Jadon’s a very talented kid and he’s still only 24 years old, so if Chelsea can get the best out of him like Borussia Dortmund did last season, then it would be a steal. There’s so much talent and so much unlocked potential there, so if Chelsea can unlock it and get him to the peak of his powers, then it would ultimately be a very, very good deal for them."
