Monty takes more wickets on english picture than he does in the subcontinent.
Well, he's had more wicket-hauls in home games than games on the subcontinent, yes, but that's not a 100% scientific way of looking at things.
For a start, much of this emanates from the West Indies series of 2007, which had little to do with good bowling on turning pitches (though it wasn't completely absent) and much more to do with shoddy batting. Unbelievably poor batting of times.
For seconds, MSP has bowled very poorly in several of his games on the subcontinent, failing to cash-in on turning surfaces - see Mohali 2005/06, Mumbai 2005/06, and Galle 2007/08. Equally, not
every pitch on the subcontinent turns: there was absolutely nothing in the wickets at Nagpur 2005/06 and SSC 2007/08 for seam or spin, both surfaces were flat as pancakes.
For thirds, there's been more turning surfaces in this country since 2004 than at pretty much any time in the previous 30 years. This started just before MSP came into the Test team - easy to forget, but Giles took 25 wickets in 3 Tests on 3 consecutive turning pitches at Trent Bridge, Lord's and Edgbaston in the middle of summer 2004, and played a vital part in the dominance of the Tests at Edgbaston and Old Trafford in 2005 too (which is often forgotten). MSP then found turning surfaces at Trent Bridge and Old Trafford in 2006, and again at Old Trafford in 2007, and cashed-in on them.
However, in his other 8 home Tests (excluding 3 against West Indies because of the execrable batting) he's not really done much of note.
But pitches in the UK and the subcontinent are not never-changing things. There is variance within the areas.
And dropping him for Harmison is just insulting.
Obviously - no-one would suggest that. Harmison is almost into the realms of "should never have played Test cricket" now.
