England v South Africa: Dale Steyn showed why he is No 1, says Morne Morkel Steyn cut a frustrated figure on the first day, and at one stage was caught on the television cameras having an animated discussion with one of the back-room staff in the dressing room after he struggled against Alastair Cook's defiance. But on day two he found his rhythm early on and although he still appeared short of reaching his full pace, his early dismissal of Cook lifted South Africa just when they needed a boost following England's dominance of day one. "Dale is the No 1 bowler in the world and we know he is going to deliver something special like that at any time," said fellow fast bowler Morne Morkel. It fires me up if I am the next-change bowler or on at the other end. Dale this morning bowled with good intensity. All we could do was follow his lead. Matt Prior said: "He is a world-class performer and is No 1 for a reason. You want to challenge yourself against the best in the world and when it was going around like it did this morning that is time you have to thrive. I wanted to thrive in the pressure to see if I could get through it. In a sick kind of way it is quite enjoyable. The morning's cloud cover helped Steyn and Morkel and in such a short snappy series luck with the conditions could decide which team are World No 1 at the end. England will be looking to the heavens when the team bus arrives on Saturday morning. "The conditions helped and we were expecting South Africa to come hard at us," said Prior. It is very easy to think it was South Africa's day but it is an attritional wicket. If we get two or three early wickets we are back in a strong position in the Test match.
