Cook celebrates his century at Lord's

Cook survived several chances before Paul Collingwood called him through for the key single on day one at Lord's.

Cook said: "You had to ride your luck, and I certainly did. Cricket is like that - some days you get the luck and it's up to you to make the most of it.

"Thank God Colly's quick. It's a great feeling and hopefully I can do it a little more easily next time."

Interview: Pakistan bowling coach Waqar Younis

Cook and Collingwood added an unbroken 221 - a fourth-wicket record for England against Pakistan - after the home side had slumped to 88-3 before lunch.

Collingwood was 109 not out at the close and saluted the fortitude of his young partner.

He said: "It's been a great day - it was important we had a good partnership.

"You have to make sure you come through your difficult patches and we did.

"Although we went three wickets down early on, we set the standards high - and hopefully we can push on tomorrow."

This is the first time a lot of the boys have played at Lords so there were a lot of tense bodies Pakistan bowling coach Waqar Younis

Pakistan bowling coach Waqar Younis admitted that his side's fielding display - five simple catches were put down - had cost them dearly.

He said: "We bowled really well but unfortunately the fielders didn't really support much.

"This is the first time a lot of the boys have played at Lords so there were a lot of tense bodies, but I thought they did well.

"Lord's has its own mysteries and it can make you tense.

"We have been catching really well but it's here in England it can be difficult, because the ball swings after it passes the stumps.
