After the signing Marseille striker Michy Batshuayi, the Blues are stepping up their chase of Everton forward Romelu Lukaku.

Lukaku left Stamford Bridge in 2014, but Chelsea are keen to reunite with the 23-year-old Belgian, and are confident of landing Lukaku for a fee around £60m.

Everton are not prepared to let Lukaku go for less than £75m however, and it seems negotiations will need to be had before both clubs can agree on a price.

If Chelsea land Lukaku, it could spell the end for fellow Chelsea forward Diego Costa.

Costa is reportedly keen to return to Atletico Madrid, where the Spainard spent three seasons before joining the Blues.

Another Chelsea star drawing interest from overseas is Oscar, as the midfielder is the subject of a bid from Inter Milan.

The Blues are adamant Oscar won't be sold, although Milan are set to test Chelsea's resolve on the matter.
