Swansea City manager Garry Monk pays tribute to former team-mate Besian Idrizaj, who died of a heart attack five years ago

The Swansea boss was a team-mate of the Austrian's at the Liberty Stadium.

Belgian football has recently been struck by two tragedies.

Gregory Mertens died three days after suffering a heart attack playing for Lokeren reserves at the end of last month. Earlier this week, Tim Nicot of recently promoted Antwerp club Beerschot Wilrijk collapsed on the pitch during a friendly game.

Mertens was 24 and Nicot just 23, far too young to be passing away from cardiac issues in the prime of their fitness.

Of course it is not the first time a footballer has suffered a cardiac arrest on the pitch. The likes of Marc-Vivien Foe, Miklos Feher and Antonio Puerta have all passed away in similar circumstances.

Others have been more fortunate. Fabrice Muamba, Clive Clarke and Stale Solbakken all survived after suffering heart attacks.

Today is in fact the anniversary of one such incident, that ended in tragedy for Swansea City.

It is five years to the day since Swansea forward Besian Idrizaj, previously of Liverpool, passed away in his sleep after suffering a cardiac arrest aged 22. He had previously collapsed playing football on two separate occasions in 2008, but had previously been given the all-clear after tests.

A Swansea team in which Garry Monk, now Swans boss, was a part of went on to win the Championship play-offs a year later.

Today he posted this Tweet in tribute to the late striker, who remains in Swansea's hearts to this day.
