Manchester City midfielder Kevin de Bruyne has spoken out about Jadon Sancho's "crazy" talent as speculation continues to link the Dortmund forward with a move to the Premier League.
The likes of Manchester United, Chelsea and Liverpool have all been touted as potential destinations for the 20-year-old, who has continued to shine in the Bundesliga this season.
De Bruyne had just a few training sessions with a then-teenage Sancho at City in 2017 before he moved to Germany, but said even then he could see what a special player he would become.
Speaking on Instagram Live with his Belgian teammates Romelu Lukaku and Axel Witsel, de Bruyne said: "He is crazy. It's weird, I trained a few times with him and he was gone - unbelievable.
"Sometimes it goes like this but it is good for him. Now if you want him you have to pay... I don't want to know!"
Sancho had scored 14 goals and created 15 assists in the Bundesliga this season before it was suspended, and is generally regarded as one of the most highly-sought after young players in the world.
Any team would reportedly have to offer in excess of £100m to tempt Dortmund into selling him, but United forward Marcus Rashford admitted in an Instagram Live Q&A on Wednesday that he would love to see him England teammate join him at Old Trafford.
"It obviously would be good, Sancho's a great player, a new generation player," Rashford said.
"It's definitely exciting to watch him become the player he's becoming. Hopefully we can all play together, that would be good.
"He plays off the cuff, he's creative, imaginative, I think they're the things you need to do to be world class."
It remains to be seen which club will make the first move in the race for Sancho, but may depend on the ongoing coronavirus crisis, which could cause the transfer window to be pushed back.
