England's strongest sides....hmmm...tough one that.
Tests, I'd go for: Cook, Root, Trott, Pietersen, Bell, Bairstow, Prior, AN Other, Swann, Finn, Anderson (AN Other because none of Broad, Bresnan and Onions have quite convinced me on this point)
ODIs: Cook, Bell, Pietersen, Morgan, Bairstow, Buttler, Wright (though I'd like to see Stokes tried), Bresnan, Broad, Swann, Finn
T20: Hales, Pietersen, Wright, Morgan, Buttler, AN Other, Bairstow, Bresnan, Broad, Swann, Finn - the AN Other should be someone who can share bowling duties with Wright...
