Despite his side's six-wicket win over Chennai Super Kings in an IPL match here today, Delhi Daredevils captain Gautam Gambhir said he was not happy at the "irresponsible" batting by his top order.

u00a0"Chasing 113 was not an easy job and you can't just bat irresponsibly. The top order need to bat with some responsibility. You can't bat just like that and leave the job for the lower order," Gambhir, who scored a match-winning unbeaten 57, said after his side's six-wicket win.
