Well, yes, but Bell had one bad series, before that he averaged about 120 in 2011...with centuries in half the innings he played.
True, Bell averaged well over 60 in each of his previous four series before UAE/Pakistan, and 331 against Sri Lanka, BUT those are less if at all relevant to series in these conditions.
That said, last time in Sri Lanka he averaged 43.50, mostly through three fifties. Doesn't mean he will average well, who knows whether his recent bad form will be more deciding than past form or not.
Prior only has one series in Sri Lanka and averaged over 40 as well, so not sure why he has been mentioned by Haarithan.
Prior
in Sri Lanka 07/08 : 165 runs @ 41.25
in India 08/09 : 88 runs @ 44.00
in Bangladesh 09/10 : 69 runs @ 34.50
in UAE vs Pakistan 11/12 : 150 runs @ 37.50
Not necessarily putting sides to the sword, but no failures.
Bell
in Pakistan 05/06 : 313 runs @ 52.17
in India 05/06 : 131 runs @ 21.83
in Sri Lanka 07/08 : 261 runs @ 43.50
in India 08/09 : 49 runs @ 16.33
in Bangladesh 09/10 : 261 runs @ 130.50
in UAE vs Pakistan 11/12 : 51 runs @ 8.50
Not clever in India for sure, Bangladesh is hardly a benchmark worth mentioning, and he had good series in Sri Lanka and Pakistan way back. Might argue he has a good series every other series so play him now and not the next one.................
