It is because all of us were saying that he should be batted up the order because the more deliveries you give him, the more impact he will have. But RCB was sending him at No.5. If you are sending him at No.5, how will the team and he do well? But AB de Villiers said it does not matter to him whether you play him at No.5 or in Mars, he will be absolutely fine," said Chopra.The former India player was particularly appreciative of AB de Villiers' exhilarating knock against the Kolkata Knight Riders on the slow Chepauk surface."The knock he played against KKR was an absolute belter of an innings.

But it was the class of AB de Villiers, who delivered once again," pointed out Chopra.AB de Villiers smashed an unbeaten 76 off just 34 deliveries in that encounter. The knock, which was studded with nine fours and three sixes, helped RCB breach the 200-run mark and they eventually won the match by 38 runs.Man of the Match : RCB vs KKR - AB de VilliersAB talks about the Chennai surface, and admits that he surprises himself at times when he gets going, as he receives the Man of the Match award.#PlayBold #WeAreChallengers #IPL2021 #RCBvKKR #DareToDream pic.twitter.com/nWhp08MdDJ— Royal Challengers Bangalore (@RCBTweets) April 19, 2021"An AB de Villiers named storm had come" - Aakash ChopraAB de Villiers played an unbeaten 75-run knock against the Delhi Capitals [P/C: iplt20.com]Aakash Chopra also spoke in glowing terms about AB de Villiers' belligerent unbeaten 75 against the Delhi Capitals which helped RCB register a one-run win."He played another knock against Delhi.
