“Defence has been one of my targets for development and I’ve been working closely with Matt [Taylor] and feel it has been coming on.
“It is just a mindset. I have never really minded defence, but it is having the focus to make it a real attribute.
“I’ve been going in and making sure that though I am never going to physically dominate people with my size, I am going low and chopping people down.
“I think Jonny Wilkinson broke that mould [non-tackling fly halves] and with the modern game, everyone has to be a defender.
“I would prefer to concentrate on attack and all that, but I have enjoyed working on my defence, and making sure that I’m not disregarding my attack too much.”
