Di Canio was proud of the way in which they dealt with Saints' attack.
"I feel 50-50," Di Canio said. "Obviously we defended for the whole game, like Fulham did against us last week.
"The defence have done an amazing job because playing Lambert, Rodriguez, Lallana and then Ramirez and Osvaldo - I tell you, this is one of the best sides up front in the league.
"Their frontline gives them a chance for them to finish in the top 10, play good football, a physical presence, energy and quality.
"My back four, central midfield and wingers, have done a very, very good job in defensive moments."
