Chelsea have offered Romelu Lukaku to Atletico Madrid as part of their attempts to sign Diego Costa, reports suggest.
This is according to The Daily Mail, who go on to suggest that such an idea has been put forward as a potential part-exchange and that the deal is subject to Lukaku overcoming his concerns over the incident of racial abuse that recently occurred during a La Liga tie between Villarreal and Barcelona at El Madrigal.
The incident involved a home fan throwing a banana in the direction of full-back Dani Alves, who gained the support of the footballing world and beyond with his remarkably composed reaction. Villarreal received a €12,000 fine as a result.
Chelsea have been linked with a move for £32 million-rated Costa for some time now, with reports earlier this week suggesting that the Premier League outfit had indeed opened talks over a potential transfer.
The possible inclusion of Lukaku in negotiations is likely to prove somewhat controversial among Chelsea fans, with many feeling that the Belgian starlet has not been afforded an adequate opportunity to impress and stake his claim for a regular starting role at Stamford Bridge.
While big things were expected of the powerful 21-year-old following his switch from Anderlecht during the summer of 2011, Lukaku has made just a handful of appearances for Chelsea so far and has spent most of his time in the Premier League out on loan.
Having thrived during a season-long spell at West Brom last season, many were surprised to see Chelsea allow Lukaku leave for a similar spell at Everton last summer.
As anticipated, Lukaku - who is believed to be valued at £25 million by Chelsea - has been a huge hit at Goodison Park, notching 15 goals in 33 top-flight appearances under Roberto Martinez.
