Chelsea have made the transfer of Mateo Kovacic from Real Madrid permanent for a fee around €50million, Marca reports.
It is believed that the transfer has also been given the thumbs up from incoming Chelsea manager Frank Lampard.
The Croatian midfielder spent last season on loan at Stamford Bridge, so he is eligible for a transfer despite their two-window ban.
Kovacic was very impressive in his debut season in England, as he made appearances and helped Chelsea achieve Europa League glory.
The two sides must, however, wrap up the deal by Sunday, 30 June, before Kovacic initial loan comes to an end.
