Things could have been drastically different for Mitchell van der Gaag.
He is widely expected to follow Erik ten Hag to Manchester United from Ajax this summer and become the United manager's No 2 in his Old Trafford rebuild.
But nine years ago, Van der Gaag stepped away from his own managerial ambitions after collapsing in the dugout as his Belenenses side played Maritimo in Portugal.
He was then 41. He had two shocks from a defibrillator that brought him back round but understandably, Van der Gaag needed time away from the game to focus on his health.
