So it;s goodbye to Kevin de Bruyne as the Beligium winger heads out the doors at SW6 to move to German club Wolfsburg.
The lad, 22, who could have playd for England, his mum came from Ealing in west London will earn the Blues the thick end of £20m.
That money will be ploughed straight back into the transfer coffers so Chelsea can resign Benfica's excellent Serbian midfielder Matic.
Matic was elbowed out of Stamford Bridge back in the heady days of 2011 when Chelsea basically gave him away to Benfica and a quite a few million quid in order to bring in David Luiz.
Matic joined the Blues in 2009 from MFK Kosice but after three run-outs in a Blues' shirt was farmed out, as is Chelsea want to their 'feeder' club, Dutch side Vitesse Arnhem.
Matic's arrival signals the end of Luiz's role as a deep-lying midfielder and he will battle it out with Gary Cahill for the centre-back slot beside rejuvenated John Terry.
Both deals are expected to be finalised by the end of play on Tuesday. Matic, will be eligible to play against Manchester United at Stamford Bridge on Sunday.
