India aims for a 5-0 series sweep against Sri Lanka in the fifth and final Women's T20I in Thiruvananthapuram on December 30. The series serves as preparation for India's T20 World Cup campaign. Key positives for India include opener Shafali Verma's destructive form and Smriti Mandhana's return to form, alongside strong bowling performances. Sri Lanka, with Chamari Athapaththu back in form, seeks to salvage pride in the concluding match.
