It is not just on the pitch that footballers sustain injuries.
What follows is an unusual tale . . .
Before Jerome Boateng became a world-class defender, before he established himself at Bayern Munich and just when he had started playing for the Germany national team, he was signed by Manchester City.
At that time, City were still building a squad after spending huge amounts of money and they had paid approximately £10.5m to Hamburg SV for young Boateng’s services.
However, fate had other plans for him.
He had injured a tendon in his knee on international duty with Germany and was flying home when disaster struck.
