Joe Root quiz: How much do you know about England's new skipper?

South Africa have been handed a timely boost ahead of the first Test against England at Lord's with Vernon Philander declared fit.

For the new skipper, the perennial question applies for top batsmen who take on additional responsibility: Will the burden of captaincy suppress Root's outstanding early Test batting record of 11 centuries, almost 5,000 runs and an average of 52.80?

Faf du Plessis, the regular captain, will miss the match as he spends time at home with his wife after the birth of the couple's first child.

Elgar has no captaincy experience at global level and the sudden change won't help a South African team experiencing a mini-decline, and under pressure.

Coach Russell Domingo smiled, as did bowling coach Charl Langeveldt, the trio of bowlers too - even Morkel who wore an extreme look of determination throughout training.

"So whilst it's obviously disappointing from a South African point of view, I think how they respond to it is going to determine how well they do in the Test match". "Our focus is on the team and getting the team to do well", added Philander. "We've got all the faith in Dean". "It can play on your mind if you're not used to it. Every time he gets the ball in hand he seems to want to run in and bowl faster and get wickets", Philander said.

Theunis de Bruyn or the uncapped Aiden Markram will replace du Plessis' in the side.

Gary Ballance is set to return to the England side after a sublime start to the season as captain of Yorkshire.

"Dean is an aggressive type of personality and he will play an aggressive brand of cricket". A Test match is a pressure, Lord's is a pressure, your first Test match is a pressure.
