Couldn't agree more.
I remember coming to the end of my time as a first team footballer. I started to be dropped and started to resent it. When I did play a nasty streak came out in me, one Saturday I kicked a young winger up into the air. I was off the pitch before the referee showed me the red card. At that point I had decided to Jack playing football in.
A few weeks later I was back in my home town and I met a man who was playing when I started out. He asked me why I wasn't at football and I told him I had jacked it in. He sat me down and told me his greatest regret was stopping playing too young, he said football is your youth, no matter what your age is.
I went back and played seconds football, l even played a season with my son. He was on his way up to the firsts and I was on my way down to the thirds. Playing that season with him was better than winning things for myself. I even played against him in a game and scored twice past him, he is a keeper. He had the last laugh as he turned out to be a much better player than me. Now his son looks like surpassing him.
So, provided Barry isn't doing himself any long term harm and somebody wants to pick him he should stick at it.
