The Blues need to finalize said deal this week before the transfer ban looming over them begins.

Chelsea needs to boost their squad before the final days of this month, mainly because FIFA's Transfer Ban will not allow them to sign more players for the next two windows.

With that in mind, Chelsea execs need to step up their pursuit of what will be their final transfer in for the next twelve months, and Roman Abramovich's employees have already done so to guarantee the player's presence at Stamford Bridge next season.

Time is of the essence to make this deal happen, especially since Mateo Kovacic, the player in question, will see his loan deal coming to an end on Sunday. Since July 1 marks the beginning of Chelsea's transfer ban, making this deal happen by the end of the week is crucial.

According to reports by Marca and the Daily Mirror, Chelsea execs have already asked incoming coach Frank Lampard to sanction this deal. The former Derby County boss has approved the transfer to take place, as he sees the Croatian as a good option to boost his midfield.

Lampard's unveiling as Chelsea boss is set to take place by the end of the week, and an announcement on Kovacic's future is expected during the weekend, if there is some sort of delay in all negotiations. Nevertheless, if the deal isn't finalized by June 30, Kovacic will have to search for other employment opportunities. Real Madrid's asking price of $56M seems to be accessible for the Blues to pay, but these final days of the month will prove just how interested the London-based club is in having the Croatian footballer around.
