Parthiv patel? when we have saha who is excellent fielder and can hit well, He shld replace Parthiv as What? Keeper??? Will Dhoni let anyone else keep? He is going to keep his place in this team forever... So why replace Parthiv with Saha..? yes of course, Replace Parthiv with Manish Pandey or Robin Uthappa or Yusuf Pathan!
if its the question of a Keeper, then we can think of Saha or others.. But the position of the keeper will be decorated by our useless captain forever (these comments are now a days said by cricket fans, yes) !!!
