Chelsea have reportedly blocked any exit for winger Callum Hudson-Odoi, amid links with a move to Borussia Dortmund.
After losing Jadon Sancho to Manchester United earlier in this transfer window, the German giants have been looking for a replacement and identified fellow Englishman Hudson-Odoi to be that player.
The 20-year-old has been an unused substitute for Thomas Tuchel's side during their first three Premier League games, and has not featured in the league since May 12.
However, despite his lack of gametime with the Blues, Sky Sports News reports that Chelsea will not allow the youngster to leave West London this summer.
After making his first-team debut in 2018, Hudson-Odoi has gone on to score 13 goals and provide 16 assists in 99 appearances for Chelsea.
