I have had 23 years to prepare for this moment but, now it is here, you realise nothing can prepare you at all. The time has come refer to myself as a 'former footballer'; this incredible journey I have been on since I was 16 is over.
My ambition was to play until I was 40, so it is scary saying the word 'retirement'. It has left me emotional and it feels weird not to be preparing for a new campaign but circumstances over the last couple of seasons have made me realise that this is the right thing to do.
To go from being a regular starter to someone whose role is limited to 10 or 15 minutes off the bench has been hard to accept. I will be 39 in January but I am physically fit and could have carried on. What I didn't want to be was someone who was thrown on to have balls smashed up to them.
1 – Volley for Stoke v Man City (March 24, 2012)
2 – Scissor-kick for Liverpool v Galatasary (September 27, 2006)
3 – Left-foot shot to complete hat-trick for Liverpool v Arsenal in front of The Kop (March 31, 2007)
4 – Scissor-kick for Portsmouth v Stoke (October 5, 2008)
5 – Finish against Man City to put Spurs in CL (May 5, 2010)
So this announcement feels a bit surreal. We have just welcomed our fourth child, Jack, into the family and the wonderful chaos that comes with a new baby means it hasn't really hit me that I haven't gone back for pre-season training. Life is hectic in a brilliant way.
But I know there is going to be a point when it really hits me. Football has opened up avenues that I never thought were possible when I started scoring goals in the Hayes and District league as an Under-10. Football, simply, made my dreams come true.
I think back to when I was 17. I was a trainee at Tottenham then but there were 10 forwards in front of me, blocking my route to the first team. They loaned me out to Dulwich Hamlet then I went to IFK Hassleholm in Sweden. Let's be honest – you would not have taken odds on me making it then.
I've had the time of my life playing the sport I love... it's time to write the next chapters

If you had told me at that point I would go on to play for England 42 times and score 22 goals, play for Liverpool in a Champions League and FA Cup final and score the goal that put Tottenham back in the European Cup for the first time in four decades, I would have had you locked up.
That, though, is what happened
