Saints rose to third place in the Premier League table with a 2-0 victory over Fulham on Saturday as their outstanding start to the season - their best in the top-flight - continues.
Their pressing game gave the Cottagers no time to settle and then superb passing left Martin Jol's men chasing shadows.
Rodriguez flicked the ball on for Rickie Lambert to score the opener, then his strike partner returned the favour for the second. Rodriguez admits the pressing game - the constant closing down and harrying of their opponents - is hard work, but worth it when the results keep on coming.
"It's enjoyable because the hunger is there which comes from the pressing and working hard. We all enjoy the pressing when we're creating chances, but the main thing for us is keeping clean sheets," he said.
"We worked really hard by winning the ball in good places and creating a lot of chances as you can see from the stats so it was a really enjoyable game.
"It was really good. We were very controlling of the game and we created so many chances and the reward is all down to how hard we've worked and to the belief which we've had from day one.
"It is no shock really. We know the performances that we're capable of and to improve upon for the next game.
"It's a great place to be at the moment, and everyone is the camp is enjoying it and loving it.
"It's great competition throughout the team from the back and up front it's all a challenge, but it's a good one and a healthy one because everyone wants each other to do well.
"It's the same throughout the team, and there's a really good atmosphere for us to be involved in.
"It's always pleasing to score a goal and to play like we did I think was unbelievable, so we're all very chuffed with it. We pressed really high and it came off for us."
