"They just do what they do very well. They don't make glaring, silly errors. Often in rugby, someone will do something slightly wrong, which leads to the next man being a bit more wrong, which leads to an error. The All Blacks don't do that first bit, so the second bit works and the third bit works well.
"If you're not making errors, you are not taking the pressure off teams. Eventually they do make a mistake, and then the All Blacks capitalise by not making errors, doing everything very well - those are what people call 'the basics', the fundamentals of the game. But the All Blacks execute them all the time, under pressure. Bang, bang, bang. When you add all of those together, you get a very good team performance.
Johnson played eight tests for the Lions from 1993 to 2001 before retiring from rugby at the end of England's victorious 2003 World Cup campaign.
Regarded as one of England's greatest ever forwards, Johnson faced the All Blacks on nine occasions during his career and played in four victories over New Zealand.
He told the Telegraph that if the Lions do the basics right then the series against the All Blacks could come down to some individual brilliance.
"Whatever you do against them, you have to do it so well that it puts them under pressure. If two teams are doing that, it might come down to someone with a bit of X factor finding something."
