"It feels great," said the former Celtic defender. “We played great football – good goals and a great night.
“I think three goals at home, a clean sheet is the perfect night for us and hopefully we can build on this now.
“It's an honour to lead my team out and I'm very proud to be captain of Southampton today and I'm glad we had the win."
