"Gloves fine. But we need to prepare for whatever can be thrown at us whether it's the opposition or the conditions and you will get all kinds of conditions whether it's frost, wind, mud or whatever, you have to play through it.

"Excellence is a habit, I have no doubt about it and the minute you think you can switch it on and off like a light then you are in trouble.
"I think that's where alot of teams can fall down and we certainly won't be doing that."
