ur right mr.narayanswami.but assume that irfan is brought back in the side and plays the first test.and by the time second test begins, rp and sreesanth will be back in the team and poor irfan will dropped, knowing that he have bundles of talents.if this happened there will be questions put on selectors that on basis they dropped irfan as he has performed very well in ODI.i think selectors had a wise thought by selecting munaf instead of irfan.so selectors can drop munaf at any point of time because he has not performed well in the past and also there would not be any crisis.
