Tottenham captain Ledley King says his love of football drives him on.
King's knee problems are well documented.
Asked what kept him going through the bad times, King said: "I love football, I love playing.
"Of course, there have been some difficult moments over the last few years.
"I don't necessarily enjoy the work I have to do inside when all the lads are outside on the training ground. It can be frustrating.
"But, as a professional, I have to do that to be able to play matches. Like I said, I love football and that is what has kept me going."
