New batting philosophy won't change but need to execute plans better: Iyer

India's "play freely" batting philosophy that skipper Virat Kohli has advocated won't change despite the opening T20 debacle against England, the rapidly-rising Shreyas Iyer said but acknowledged that it needs better execution in the coming games. India posted just 124 against England in the first match here on Friday , unable to cope with a very disciplined pace bowling show by the visitors, spearheaded by Jofra Archer and Mark Wood. England took just a little more than 15 overs to overhaul the target.
