Chelsea may agree with the contract for loanee Mateo Kovacic – despite their potential transfer embargo.
The blues awaits to hear the outcome of their appeal against an embargo that will ban them from registering players this summer.
But Los Blancos offered the Londoners a chance to extend the loan to Kovacic at Stamford Bridge for another season.
However, it will come with a compulsory option to buy an agreement worth about £ 26m, which Real insisted must be signed by May 5th.
It could cause a problem, but of course the extension of an existing loan would be a way around this issue.
Kovacic is ready to stay in London and not appear in Zinedine Zidane's plans in the capital of Spain.
But the Croatian made only 14 starts in the Premier League, failed to score and secured only two assists.
Despite his struggles, Mauricio Sari recently said he would like to keep the midfielder.
"I would like a lot that Kovacic will stay with us," the Italian said.
"You know very well that in this position we have some problems because we have only Georgiego. In my opinion, Kovacic could become a very good center midfielder."
Kovacic did not start for Blues after a 2-1 win over Cardiff last month, playing twice as a substitute in the four matches in the meantime.
