12pm What an extraordinary innings. Just 101 overs from pillar to post, barely a full day's play, but a run-rate in excess of 6.5 from first over to last, including four centuries, two of the most expensive overs in Test history, the most expensive figures for a debutant in Test history, and a towering total of 657 on the board. It's not quite the 1000 that Zak Crawley had targeted, but it'll take something special for Pakistan even to get close to parity. How do they skin this one? We'll find out soon enough.

Mustafa Moudi : "Fun Fact: England has scored this mammoth total without a single half century. All those who reached 50, successfully converted them into centuries !!"

Hammas: "I feel England is 343 runs short here."

Jai: "Since yesterday end of the day, people have been talking about England going for 1000 runs..... but in the other match AUS had better chance if they could have continued with out declaring...." Yeah, but they batted far too slowly to earn the right to have a go...

Rosh: "What's changed between yesterday and today? Are the English simply not being as cautious? " Yes, they were watchfulness personified on day one...
