A recent report in L'Equipe suggested a swap deal involving David Luiz and additional funds would be sent to Atletico Madrid in order to have Diego Costa at Chelsea for a reduced fee than the speculated £35m it would cost to convince the Vicente Calderon side into allowing Jose Mourinho to enter personal negotiations with the player through a traditional cash transfer.
Costa is, undoubtedly, one of the hottest, potentially available, commodities in the upcoming summer market due to his penalty-box skill-set, his engine and his prolific goal-scoring.
Considering the abundance of chances created by the "three" in Jose Mourinho's traditional 4-2-3-1, the "one" would revel if he was a positionally-disciplined final-third bound attacker like Costa, as opposed to more of a withdrawn forward who creates as many as he does score, like previous target Wayne Rooney.
However, considering Chelsea's success in closing up shot and keeping their sheets clean in significant matches of late - against Atletico Madrid in Spain - should the acquisition of Costa come at the sacrifice of Luiz?
The player himself reportedly prefers being deployed in the heart of defence, yet he is increasingly utilised by Mourinho in midfield. At Atletico, he may get his wish, while the Blues have alternative players they can use in place of Luiz.
By reducing the overall cost of a Diego transfer, bringing the £35m price down to compensate for the addition of Luiz (valued by transfermarkt.co.uk at £23m), then Mourinho will also have further funds for other areas in his team that need reinforcement - chiefly, full back.
