All-round greatness of South Africa's Jacques Kallis faces a real test against England, says Michael Vaughan He can score quickly at times but it is his way of being able to read situations that sets him apart. He knows what is required at the right time either with bat or ball. He knows when to grind it out or move up through the gears. Some people think he could move through the gears quicker when batting, and that is probably a fair argument on occasions, but the majority of the time he knows what he can do at the crease and believes South Africa have a better chance of winning if he stays there. The South African lads obviously know him very well, but I don't think we really have any idea about the real Jacques Kallis. He had a year at Glamorgan in 1999 and they loved him. He was team man and part of their social network but also very determined to win games for his county side. But playing against him for England, he never really said much and kept himself to himself. He tried at captaincy for a while but it never fitted with him. There are some who are just not made for captaincy but I would love to know how much he talks to Graeme Smith from second slip about tactics. I played about 20 Tests against South Africa and he never chirped once while I was batting. When he bowls he is aggressive with his body language. He will always follow through and stare but never says anything. He bowls the odd quick bouncer and then full swinging deliveries. He has bowled some really quick spells, particularly at Headingley in 2003. He bowled down the hill and I nicked one to the slips. But I think he is a more skilful bowler now. He understands he has the holding role, and if the team needs a wicket he knows which buttons to press. But it is true we haven't seen the best of him in this country. His average in England with the bat is 29, half of his normal Test record. He has come up against England attacks that have been very good and this country can be a place where, if you don't find a rhythm and groove early on, it is hard to get going. This tour will tell us if he has learned from the past. You are never really in against the swinging ball in England. If you reach 50 in South Africa you are set up for a score and can help yourself. But in England you can be out at any time. Down the years Matthew Hoggard bowled well at him and Freddie Flintoff always gave him problems bowling full at the stumps with a bit of aggression. On this tour James Anderson will be his nemesis. Get it moving around, catch him on that front foot and we will have success. He has been renowned for being mentally tough and in the zone but sometimes as a batter you get a creeping fear that certain grounds and certain countries do not work for you. I used to go to Bristol and never get a run. It just happens that way. He will want to go off on a high but I don't care who you are, against this England attack you can be out for low scores.
