Joe Aribo, a Nigerian international who has been a vital member of Southampton’s squad since his return from the 2023 Africa Cup of Nations, showed off his skills in the first half by giving Southampton the lead in the 12th minute.
Even though they dominated the first half, Southampton’s lead at halftime was only 1-0.
After coming on as a substitute, Famara Diedhiou tied the score from close range, making Southampton pay for squandered opportunities.
In injury time, teenage Cian Ashford completed the win for Cardiff with a deflected strike from 25 yards.
