Asked if he has been told already, however, that he will definitely stay in charge when the selectors name their squad later this month for seven one-day internationals in Sri Lanka, Cook said: “No, I haven't.”
He can only hope so, but with a little more confidence than he perhaps had on the journey north to Leeds this week after England's previous trouncing at Edgbaston.
“We did (badly need to win),” he added. “It becomes slightly frustrating - because if you play like that, you'll win a lot more games.
“We did a lot of things very well, and a lot of things we know we had to do and haven't been doing in previous games - like one of those guys, top four or five going on and getting a big score, and then the others can support him.”
Root's methods were an endorsement for the tactics England intend to stick to, especially at home - top-order batsmen backing themselves to play long innings, and accelerating with wicket resources intact.
