Chelsea have knocked back numerous bids from Bayern as they attempt to get the young forward tied down to a new deal, but interest in the player is showing no signs of waning as the summer window fast approaches.
Dortmund are now reported to have declared their interest in the player as doubts surround the future of their own starlet, Jadon Sancho, who is said to be a target for Manchester United during the close season.
United could be willing to pay as much as £100million to snap up Sancho, which would leave BVB with plenty of money to draft in a replacement, and they are said to have identified Hudson-Odoi as the man they want.
Hudson-Odoi, who has just received his first call up to the England squad, has so far refused to pen a new deal with Chelsea as he is keen to play regular first-team football, something he is not getting at Stamford Bridge.
Chelsea were knocking back bids of £30million from Bayern in January, but their valuation is sure to have risen even further if they do back down and decide to cash in.
