There's not much I have in common with Usain Bolt. He's certainly a little quicker than I was at my peak.
But we shared the same doctor when it came to turning to someone in need of urgent repair.
When I was a Liverpool player, I regularly used the tricks and skills of Doctor Hans-Wilhelm Muller-Wohlfahrt to rescue me from another injury.
Now Bolt, the greatest sprinter of all time, is visiting his Munich clinic to try and be fit for the London Olympics, which start in 18 days.
I've read in these pages about Muller-Wolhfahrt's methods being described by a senior figure within the US Anti-Doping Agency as 'Frankensteintype experiments'.
I'm not sure what that means, although with me he would use fluid taken from the comb on the head of a hen to lubricate a knee joint that had been eroded by a succession of injuries.
He would tell me that it was like 'high quality oil for the engine of a car'.
He concluded that the fluid taken from a hen's comb would lubricate the knee and allow greater movement. I was happy to do what he suggested to have the confidence to play again.
I've also read about him prescribing goat's blood injections for hamstring injuries.
His methods are successful, which is what has drawn Bolt around the world from his Jamaican training camp and why so many go to see the man they call 'healing Hans'.
Among the sportsmen and women who have stepped into Muller-Wohlfahrt's dimly lit office are Steven Gerrard, Ronaldo, Jurgen Klinsmann, Dame Kelly Holmes, Paula Radcliffe, Michael Owen, Jose Maria Olazabal and Maurice Green.
There is talk of controversy about Muller-Wohlfahrt's methods, but I won't have a bad word said against him.
I saw him many times and there was never anything untoward suggested.
This is not a back-street quack.
He is still Bayern Munich's team doctor, world renowned and a master of his art - and they didn't seem to be doing too badly the last time I watched them in the Champions League Final.
Good Hans: Doctor Hans-Wilhelm Muller-WohlfahrtBolt versus his Jamaican training partner, Yohan Blake, is the golden ticket for London.
Last weekend, Blake beat Bolt, the fastest man on the planet, in back-to-back races over 100m and 200m.
Bolt then withdrew from the Diamond League race in Monaco and the alarm bells are ringing.
Nobody wants him to miss these games, surely not even Blake.
Athletes generally turn to Muller-Wohlfahrt as a last act of desperation, having exhausted all the local practices and medical skills of those they have been closest to.
You can't tell me that Bolt has flown all the way from Jamaica to Munich without trusting Muller-Wohlfahrt's art and without searching for a solution a little closer to home.
Like me, he must trust his methods and rely on his advice.
He is renowned for helping sportsmen and women, like Bolt, recover from hamstring problems.
When I tore a hamstring playing for England, I was out for five months. He is getting sportsmen back on track within five weeks.
I only wish I had known about him then.
Golden ticket: Yohan Blake will ensure the 100m is the biggest-watched Olympic eventIt appears Bolt has a back problem which may have affected his right hamstring.
It doesn't sound as if Bolt has suffered a tear, more likely a tweak and if he is unable to trust his hamstrings it might explain why some of his times have been sluggish, by his standards.
Didi Hamann, the former German international, first recommended Muller- Wohlfahrt to me when I didn't know where else to turn.
I hopped on a plane with the Liverpool physio, hoping we could find some answers.
When you are injured and desperate, you will travel the world looking for the right person, with the answers you crave.When I first met him, I was anxious, but he made me feel welcome and relaxed.
He was in his 60s (he's 70 next month), but he had the skin of a man 20 years younger, with a shock of hair and healthy outlook on life.
He believes in the power of positive thinking, he is a charismatic man who convinces you he can find the answers.
Most doctors do, but he backs it up with achieving success.
His staff are dressed from head to toe in white and he is there, overseeing the treatments and working from 7am-11pm, trying to find the solutions for a conveyor belt of people, including the general public, who come looking for answers.
My club, Liverpool, paid for my treatment through insurance, but when I bumped into Hans at a recent Champions League game, he asked me how my knee was and I told him it was still causing me hassle.
He told me to come and see him and after some treatment I asked him where I could pay the bill.
He said: 'There isn't one, Jamie.'
It was a kind gesture from a very skilled man. Bolt is in Safe Hands.
