Ex-Newcastle, Sunderland and Manchester United striker Andrew Cole has questioned whether more can be done to help protect footballers from heart problems following the death of Cheick Tiote.
Tiote died this week while training with Chinese club Beijing Enterprises. His family remain in the dark over what caused his sudden and tragic death at the age of just 30 as they await the results of a post-mortem, but a suspected heart attack appears the likely cause at this stage.
Tiote's death comes little under two months after former Aston Villa defender Ugo Ehiogu, Tottenham's Under-23 coach at the time, died of a cardiac arrest, while Fabrice Muamba (2012) and Marc-Vivien Foe (2003) both also collapsed on the pitch due to heart problems, with the latter dying.
"If someone is only 30 and they pass away, the question that is naturally going to be asked is 'Why? What's gone on there? Why has he passed away so early?" Cole told BBC Radio Five Live's Sportsweek programme.
"It's a strange one. Cheick Tiote hadn't been in China that long - a few months - so he must have had a medical to complete the transfer. Was nothing picked up in that medical?
"You'd like to think that things have moved on these days and that these types of things could be picked up in medicals.
"Players are going for vast amounts of money so you'd think the tests would be very stringent, there's no cutting corners if clubs are parting with large fees. But it's just so strange that players are passing away or having to retire with all the same sorts of problems.
"Is anything actually being done? Is it being looked into? We need to nail it down and get to the bottom of why and what it is, because it seems to be happening to more and more professional footballers - fit, strong men."
Cole himself has been unwell recently and is currently recovering from a kidney transplant. The 45-year-old suffered kidney failure in 2015 after contracting an airborne virus.
His 28-year-old nephew Alexander donated a kidney, and Cole said: "It has given me my life back again.
"I was struggling before I had it, finding everyday chores very difficult. But since having the transplant things have been different. It's been tough, but fingers crossed I can keep recovering
"I was fortunate enough to have a transplant and it has worked very well for me. People would say to me that I'm still fit and a young man, but illness has no age. If it's meant to be you, then it's meant to be you."
Cole has returned to his role as an ambassador for Manchester United and intends to coach a club legends team to face Barcelona in Spain at the end of the month.
