Chelsea have been angered by the public nature of Bayern's pursuit, with sporting director Hasan Salihamidzic confirming on Wednesday that the German giants "absolutely want to sign" Hudson-Odoi this month.
Sancho believes Hudson-Odoi can be "the next one" off England's current production line of talent, and revealed he has had talks with the Chelsea 18-year-old about life in Germany, amid a £35m bid from Bayern Munich. "We've played with each other at England". He's very good, very talented, fast and good dribbling skills.

"I have told him the Bundesliga is a nice league".
Hudson-Odoi has been the subject of several offers from Bayern this winter, but Chelsea want to keep their star.
Hudson-Odoi, who made his first-team debut in the FA Cup in January previous year, made a second successive start in the Carabao Cup first-leg defeat by Tottenham.More news: World leaders shun Venezuela as 'dictator' Maduro sworn in
He provided assists for two goals in the FA Cup third-round win over Nottingham Forest.
"I know only that for me he is a very important player. He is very young but now he is improving especially in the defensive phase", he said. "Now he needs to improve in some movements without the ball, but he is working very well at the moment so I am very happy with the player and would like to have him in the future". Then I don't know what to say, I don't know the situation.
Sarri, who celebrated his 60th birthday on Thursday, said he recommended Chelsea need to recruit two players, but declined to say their positions.More news: Led coalition says Syria withdrawal has begun
