Graeme Souness urged fans to learn CPR and help save lives.
The 69-year-old former Liverpool, Newcastle and Blackburn boss has joined the British Heart Foundation to raise awareness.
In a poll of 2,000 adults in the UK commissioned by the BHF to celebrate Heart Month in February, 45% did not recognize the signs of cardiac arrest.
At Euro 2020, Christian Eriksen suffered cardiac arrest while playing for Denmark, while several matches, including Newcastle and Fulham, were cut short due to medical emergencies in the crowd.
Souness has her own personal experience with coronary heart disease, having received the diagnosis in her 30s while undergoing a triple bypass.
The Scotsman, a longtime ambassador for the BHF, is now urging fans to learn CPR with BHF’s online tool RevivR — which teaches CPR in 15 minutes.
He said: “CPR is a game changer and may be the most important lesson you will ever learn. With ReviR, in just 15 minutes – as long as a break – you will have the skills you need to save your life.
“Every fan of every football club in the country can make a difference, so please join the BHF today and let’s come together to create a new team of lifesavers.”
