Broad, Pietersen, Prior, Trott and Anderson all did enough in the 1st Test so they should get the series (in Broad's case not a given beforehand) Tremlett probably too, although I thought I saw somewhere today he might be a doubt. Bell just about, he, Strauss and Cook will be looking for runs.
Swann is our number one spinner, can't see him being left out despite a modest performance (2/114 and 24 runs)
Morgan is the one player I've always wondered if he should be in the Test side. He averages a modest 34.08 from 10 Tests, had a pretty good series against Sri Lanka but didn't make most of two starts against Bangladesh and made two 70s against Sri Lanka without going on. Since his 130 against Pakistan he's made 232 runs in 11 innings @ 23.20. I'd keep him for ODIs, bring in a batsman who can bowl a bit of spin preferably, but bowl something like as well as Collingwood would be very handy (Bopara?) He may well get the rest of the series, I'd be looking ahead to the tour and rest him for the ODI series
