Ahead of his 100th Test, the Sky Sports experts look back on the career of England captain Alastair Cook.

The 28-year-old made his debut against India in March 2006, with Cook impressing immediately with scores of 60 and 104 not out as England drew the first Test in Nagpur.
The Essex opener has gone on to score 7,883 runs at an average of 47.20, with 25 centuries and 33 half-centuries.
Cook's top score of 294 came against India in 2011 at Edgbaston, while he also scored 235 not out against Australia at the Gabba in 2010.
And ahead of his milestone appearance, Sky Sports' experts Down Under look back on Cook's Test career.
"It's a fantastic achievement and a remarkable coincidence that coming here both captains - they could have had their 100th Test match anywhere - and they're having it in Perth, together.
"You couldn't get two more different characters on or off the field either - they have completely different styles.
"For Alastair it's great and great reward. I was brought up with him in the Essex days and he was playing Essex second team and occasionally I'd play with him when I was going through one of my lean trots. I'd go and see him in the second team and to see him now as England captain and playing his 100th Test match.
"I know he's had a difficult month or so but the way he has gone about his cricket his been phenomenal. The thing that stands out about Cook is that he's set his whole career up about proving people wrong and this is the time to silence the critics as Clarke has done the last couple of games."
"Anybody who plays 100 Test matches has obviously had a fantastic career and very successful career.
"For an opening batsman and a captain to have played that many games says a lot for your mental fortitude and strength of mind.
"A lot of Alastair Cook's hundreds blend into one. They are all very similar, not too many eye-catching strokes in those innings. He's a very phlegmatic player with a simple technique and he chooses his strokes carefully.
"The context has often been important. I was there in Nagpur in 2006 when he made his debut and he flew over from the Caribbean at late notice. What he showed in that match was his ability to adapt to conditions and adapt quickly."
"I remember when he came out to replace Marcus Trescothick on the India tour in 2006 and he impressed straight away at just 21 years of age.
"I remember the first ball bowled at him, it was a bouncer, and he whacked it away for four. Even at that age he looked very cool, calm and composed - a bit like Joe Root now.
"Has it surprised me that he's made it to 100 Tests? Probably not. His record is phenomenal, it's up there with the best England records of all time and he's outperformed what most people thought of him in those early days.
"It's a great testament to his consistency. He's been phenomenally consistent and hopefully he'll mark his 100th Test in style."
