Well, firts of all RCB needs to do a lot to their bowling.we need someone in absence of vettori who can keep the economy rate low.today against KKR arvind and langvelt have to be at their best .sourabh tiwary must score a 50 today. he is not being a usefull batsman for RCB.he must be sent at top order today.Well if sourabh and langvelt perform greatly today remaining guys will keep doing what they have been doing til now.So no stopping RCB if it performs like it has been performing in previous matches. Best of Luck RCB.
