Alastair Cook announced he will retire from international cricket following the conclusion of the fifth and final Test against India at the Oval.

The opener brings the curtain down on a 12-year career with England, during which time he became his country's all-time leading run scorer in the longest form of the game.

Cook's time as a Test batsman will be bookended with matches against India, having made his debut in Nagpur in March 2006.

A dozen years later, he will bow out against Virat Kohli's number-one ranked side in what is sure to be a celebratory occasion in London, especially with England having already secured a series victory.

Below, we look at some of the key numbers that underline Cook's status as one of the game's great batsmen.

160 - Test matches played, between March 2006 and September 2018. The clash at the Oval will be Cook's 159th in succession - more than any man in history.

12,254 - Runs scored for England. That puts him more than 3,000 clear than the next best for his country, Graham Gooch (8,900). Cook stands sixth in the all-time list.

26,086 - Balls faced for those runs. Or, if you prefer, 4,347 overs and four balls.

294 - His highest score in Tests, versus India at Edgbaston in August 2011.

44.88 - Cook's Test average. Should he be dismissed twice at the Oval, he would need to score 121 across the two innings to finish with an average of 45.

32 - Test-match hundreds, putting him joint-10th on the all-time list alongside Steve Waugh. Kevin Pietersen (23) is his closest challenger in an England shirt.

56 - Fifties, giving him a conversion rate of 36 per cent.

173 - Catches taken, the majority of which were from first slip.

1 - Test-match wicket, against India at Trent Bridge in July 2014. The batsman? Ishant Sharma, who edged behind to Matt Prior.
