Chelsea will let Romelu Lukaku leave on a permanent basis for Tottenham if they can secure the services of Atletico Madrid superstar Diego Costa this summer, according to The Daily Mail.
Lukaku has enjoyed a successful season at the Goodison Park outfit and has scored 12 league goals for Roberto Martinez's side this term.
However, it appears that 'The Special One' will only let the Belgian forward depart Stamford Bridge if priority target Costa is signed for £31.5m.
Costa has had a fine season in La Liga in this campaign and only sits behind Cristiano Ronaldo in the scoring charts in Spain's elite division. The Brazilian-born Spanish striker has struck 26 league goals and also played a crucial role in his side's Champions League success so far.
And now, with Chelsea ready to make a move for his services, it remains to seen as to whether the hitman is tempted by a switch to Stamford Bridge.
For now though, the Chelsea boss will be focussing on his side's Champions League quarter-final first leg clash with French giants Paris Saint-Germain tonight. The Blues will be desperate to gain a positive result ahead of the return leg at Stamford Bridge next week.
