Cook's innings is remarkable particularly as he's been on the field for the entire match so far. I think he went off with a couple of overs to go before the close on day one but other than that, at lunch on day 4 he's still out there.
400-3 at lunch, Cook 204, Root 76. That was a pretty good session for England. I wonder if they will try and force a result? It will take a pretty special bowling effort on this pitch but Bayliss is a pretty attacking coach so you never know.
