Mauricio Pochettino hailed Saints’ “brave” performance in their 3-1 victory over Liverpool.
Saints dominated the Reds for the vast majority of the game and ran out deserved winners in front of a record St Mary’s crowd.
The result helped push Saints seven points clear of the relegation zone and closer to Premier League survival.
Pochettino, who got his second win as the club’s manager, said: “There were many positive aspects, especially seeing how brave my team was going head-to-head against them and really pushing forward.
“We didn’t allow them to play at any given moment and when we had the ball we really tried to pursue our philosophy of football.”
Saints’ performance had echoes of the 3-1 victory they secured over Manchester City last month, and Pochettino said he was thrilled with the manner of the result.
“I think we played well today and I think we fully deserved the win,” he said.
“Overall, we have just maintained the same trajectory since I got here, and my team has been playing the same way.
“It’s been really important that my team keeps on believing in the philosophy that I’m trying to instil in them.”
