Ian Maatsen is set to join Borussia Dortmund on loan from Chelsea until the end of the season.
Maatsen almost left Chelsea last summer, when Burnley had a £31.5m offer accepted on deadline day to sign him after a successful season on loan there, but the Dutchman decided to stay at Stamford Bridge. He has started only one Premier League game under Mauricio Pochettino despite Chelsea’s injury problems.
