Ajax's veteran defender Daley Blind has been diagnosed with a heart condition.
Blind played an integral role in the Dutch sides manic march to the Champions League semi-final last season only to fall seconds short of the Madrid final.
Blind suffered from dizziness during his clubs most recent Champions League clash with Valencia and was subsequently taken for tests.
It was discovered that Blind was suffering from inflammation of the heart muscle - known as cardiomyopathy, and he has been fitted with a subcutaneous implantable cardioverter-defibrillator (an electronic device that constantly monitors his heart rhythm).
While the severity of the ailment is yet to be disclosed, Blind's involvement at Euro 2020 with the Netherlands could be in doubt.

An Ajax statement posted online said: "Daley Blind has been diagnosed with heart muscle inflammation.
"The central defender has undergone an extensive medical examination in recent days, following the dizziness that briefly bothered him during the Ajax v Valencia match.
"It was then decided to place a subcutaneous ICD with Blind, a device that is applied under the skin."
We can only hope that the situation is not as serious as it sounds and Daley doesn't have to take any further drastic action.
Heart issues are not to be trifled with though and Blind may have no choice but to scale back on the amount of football he plays.
With Ajax crashing out of the Champions League, it won't be a surprise to see a lot less of Blind going forward this season.
With Euro 2020 on the horizon, he will be desperate to pull on that famous Orange shirt one last time.
Get well soon, Daley.
