Chelsea have reportedly renewed their interest in Shakhtar Donetsk attacking midfielder Douglas Costa.
The 24-year-old recently revealed that the Blues did table a bid for his services in January, only to be knocked back by Shakhtar.
However, Jose Mourinho remains keen on bringing the two-time Brazil international to west London and has already made an improved offer, according to Le10 Sport.
The Ukrainian giants are reported to want somewhere in the region of £22 million for Costa, whose contract in Donetsk expires in 2018.
