Cook at ease and ready to complete circle

Turn back a year, to the two-Test series against New Zealand, with low expectations of a team rising from the fiasco that was the World Cup, and few would have foreseen the bright summer that captured the public's imagination and reinvigorated a young and exciting England side.

Turn back another, and the knives were sharpening for whoever was left standing after an Ashes pasting that left the team in tatters and ended several careers.

It seems astonishing, therefore, that England are just two series wins away from holding all nine bilateral Test series trophies. If they succeed against Sri Lanka and Pakistan this summer they will complete a set that few would have contemplated possible two years ago.

"I think it would be a great achievement," Alastair Cook, England's captain, said. "People have spoken about it over the last couple of weeks and I don't think there's any harm in that if it inspires us to do it. But actually achieving that will be hard work. We know that and it's not going to be given to us against two good sides."

In a testament to his durability, Cook has weathered the turmoil, led each new round of new eras and now stands on the cusp of becoming the first English player to reach 10,000 Test runs.

That he will reach the milestone as England captain is, he acknowledges, down to his stubbornness and determination never to quit. It will be fitting, too, if he passes the mark against Sri Lanka at Headingley; it was during England's loss in the corresponding Test two years ago - as Angelo Matthews and Rangana Herath frustrated England's bowlers with a match-winning partnership - that Cook reached his nadir as captain and was on the verge of quitting, in his own words "close enough that you wouldn't want to get any closer".

"I just thought about that what had gone on since January 30 that year to what had gone on there really. It was a tough three or four months off the field as much as on the field," he said.

"I've never really quit on anything. I probably had about two percent left in me saying if you walk out now you still have a bit more to offer that side really. So I suppose me being stubborn, probably, and not quitting… I don't really want to be known as a quitter.

"It was certainly a tough day, the fourth night was tougher than the fifth," Cook said of England's Headingley defeat, which was confirmed from the penultimate ball of the Test. "I was very proud of the way we battled on the fifth day but the damage had already been done. It's an amazing game of fine margins, that series. Minus the last ball [that] didn't quite carry [at Lord's] and then Angelo Mathews nicked a ball which didn't quite carry and then he went on to get a brilliant 160, which won them the game.

"It was a game of fine margins and Sri Lanka came out on top and thoroughly deserved it. It was a real tough moment for me as a captain, there's no doubt about that, but I'm glad I hung in there for what's happened since."

While Cook leads a far more settled side into this series, questions surround those batting alongside him in the top order, despite a successful tour of South Africa. But while he admits the consistency has been missing from the top three, Cook is keen for Alex Hales and Nick Compton to tune out the dissenters and embrace their own, contrasting styles of play.

"Until someone really grabs that opportunity and nails it then there's always going to be questions asked," Cook said. "Alex is the man in possession at the moment and the way he played, certainly the one-day series against South Africa, five scores above 50 - the way he played, certainly watching back home, showed everyone he's not just a T20 specialist. He played proper cricket. He wasn't just whacking the ball. I thought he played some excellent shots and he looked really controlled. He can certainly play at this level.

"As always with these things you want to get a big score to try and prove that to people and do it consistently. That's his challenge and it's the same for Nick as well. He got a really good 80 at Durban and that was only four games ago and that helped set up in tricky conditions a score that we were able to push on and win. The guy's a fighter and he's just got to relax and play."

Cook can no doubt relate to Compton's situation - that of being a more traditional top-order batsman who excels in blunting the new ball and accumulating, rather than accelerating, in a world where aggressive batting has become far more fashionable.

But many of Cook's 9,964 Test runs to date have come via nudges and nurdles, and many more will likely follow in the same manner. As he leads his side out for the first session of England's summer campaign, the man who was 98% sure he would hand in his notice is now sure of his place.

"It's probably taken me three years to feel comfortable in the job and hopefully I can carry on for a bit. While I'm still enjoying it and while the guys are still responding I'm staying there."
