Cook finds right ingredients once more
Watch highlights of day four
Alastair Cook toasted England's new coaching era with his second LV= County Championship century of the season as Essex batted out a draw with Surrey at the Kia Oval.
The England captain fired 127 in a second-innings total of 258 for four, with Ravi Bopara adding 42 to his first-innings 49 in the Division Two clash.
Cook backed up his mammoth 181 against Derbyshire at Chelmsford with another assured knock before the evening confirmation that Paul Farbrace will be Peter Moores' assistant in the England set-up.
New England boss Moores will want chief lieutenant Cook on top form and the 29-year-old left-hander looked somewhere close to those lofty standards as he brought up a 47th first-class century.

Surrey started day four by resuming their first innings on 217 for six, but failed to spend the kind of time in the middle coach Graham Ford had demanded.
Left-arm paceman Tymal Mills bowled Chris Tremlett for six and removed Jade Dernbach without troubling the scorers.
Jason Roy's 46 from 61 balls proved the final resistance, but even his battling innings came to a premature close, snared leg-before by David Masters.
All-rounder Zafar Ansari's continued absence with concussion meant Surrey were done and dusted at 237 for nine.
The hosts' tail wagged for less than five final-day overs, handing Cook centre stage and he was quickly into his stride as Surrey failed to match their first-innings bowling accuracy.
Jaik Mickleburgh edged Matt Dunn through to Steven Davies, Surrey's young seamer adding another victim to his first-innings five-wicket haul.
Essex eased to lunch at 82 for one with Cook 40 not out though, and continued in much the same vein after the interval.
Cook notched a fifty from 90 deliveries with the ninth four of his innings.
Tom Westley played his way to a creditable 42 and a 78-run partnership with Cook, before he was cleaned up by Dernbach with Essex 128 for two.
Commanding complete control, Cook cruised to his century in 160 balls, finding the rope on seven further occasions.
Essex reached tea at 204 for two, with Bopara 28 not out and Cook on 107.
Bopara could not reach a half-century as Surrey youngster Dominic Sibley bowled the England man to claim a memorable maiden first-class scalp.
Cook eventually succumbed to a Rory Burns delivery that ended a 202-ball stay.
Greg Smith and Ben Foakes were unbeaten on 16 and four respectively when the teams shook hands.
