Northampton Saints' Lawes wants to add 'fear factor'
Northampton Saints forward Courtney Lawes says he can keep his trademark hard tackling legal.
Lawes told BBC Radio Northampton: "I realised I needed to stay on the right side of the referee.
"It's a big part of my game and [what I] can add - a little bit of fear from the opposition."
Lawes continued: "The crowd is always going to be for the home team and get on your back if [the tackle] is a bit late.
"You've got to put that to the back of your mind and play your heart out for your team."
Saints have now won five matches in a row ahead of their Heineken Cup clash with Munster.
"There's loads of things to improve on," Lawes added. "[Director of rugby] Jim Mallinder wasn't completely happy with us.
"Some of our kicks were a bit astray and we can do a lot better at keeping hold of the ball. Once we get a lot of ball, we're just unstoppable."
