Swansea winger Dyer admits career may never have started
He said: "While Crouchy had growth hormones to help him as a youngster it was a bit difficult for me because I was told I was not strong enough or tall enough.
"Despite what was being said it never came into my mind that I wouldn't make it, especially not because of my size.
"People talk about small players but there have been some fantastic small players in the Premier League.
"I think anyone can play in the Premier League as long as they are good enough. It's not just the big boys who do it.
"Look at someone like Gianfranco Zola - nobody said he was too small.
"Some of the best players are small, look at Lionel Messi. He's not too bad.
"And while I might not be the biggest I give the opposition a battle by using my pace."
