Chelsea are one of several Premier League clubs who could be affected by collapsed TV deals from across Europe.
According to the Daily Mail, broadcasters have failed to make payments to clubs in Spain with the season now on hold, meaning clubs may be unable to pay the transfer instalments due in June.
This could be bad news for the Blues in relation to Eden Hazard's move to Real Madrid last summer.
The Belgian waved goodbye to Stamford Bridge as he joined the La Liga giants for £90million shortly after the Europa League final win over Arsenal, with the fee being paid out in instalments.
It was also reported that the fee could rise to as high as £150m.
However, the west London outfit are fearing the worst regarding receiving the initial full amount in full.
In addition, the report states Hazard’s deal is one of 54 transfers with outstanding payments to be made from a club in France, Spain or Italy to a Premier League side.
Chelsea are also waiting on the remainder of the money from the transfers of Diego Costa, Juan Cuadrado and Bertrand Traore.
In total, Premier League clubs sold players for a combined £851m to clubs in France, Spain and Italy over the last four years, and with a significant proportion of those fees have yet to be paid they could now be in jeopardy.
The fear for Chelsea is that not receiving the next instalment of Hazard's transfer could affect Frank Lampard's budget this summer.
Although it remains to be seen how much the Blues head coach is affected given the club had a transfer ban last summer and opted not to spend a single penny in January.
After swapping London for Spain, Hazard outlined the biggest difference between the two clubs.
"At Chelsea when we lost, we were disappointed, like the fans, but I never felt it was a disaster, it’s different in Spain," Hazard said last September. "I think that here the fans are really fans, football is everything to them and they need players to give everything, in England there aren’t so many fans.
"Of course, people there like football and everyone, be that young people, adults or teenagers, are really interested in football, but they aren’t so fanatical about their teams."
