Antonio Rudiger will be unveiled as a Chelsea player in the next 24 hours.
The Roma defender is undertaking his medical today following a £34million move.
The current champions have moved quickly to tie up the loose ends of the deal after losing out in the race to sign Romelu Lukaku.
Antonio Conte will be unhappy to have lost out in the race for the Manchester United forward but he has been desperate to return to Serie A and sign a defender.
It is only Chelsea's second arrival of the summer following their capture of Manchester City keeper Willie Caballero.
Rudiger has been a vital part of the Roma side that qualified for the Champions League last season.
