Former champions ATK and two-time runners-up Kerala Blasters FC will look to renew their rivalry when they face-off in the opening match of the Indian Super League (ISL) football tournament here today.

The fifth season of ISL will witness high-octane action as 10 elite teams compete for the coveted title. The ISL-5 is expected to be the longest, spanning over six months with three breaks — two FIFA windows (in October and November) and one for India's preparatory camp for the 2019 AFC Asian Cup. Both ATK and Kerala struggled to hit the ground running last season, with ATK faring worse than the two, finishing a nightmarish nine out of 10 teams and saw three coaches at the helm.
