The Saints on Saturday picked up their second win since Pochettino succeeded Nigel Adkins in January, beating Liverpool at home 3-1 - the same scoreline they registered when seeing off Barclays Premier League champions Manchester City at St Mary's last month.
Rodriguez netted Southampton's third against the Reds and the 23-year-old feels the south-coast outfit - currently 16th in the table, four points clear of the relegation zone - are thriving under their new Argentinian boss.
"I've got a little bit more belief in myself and the gaffer, full credit to him, he's given me a bit of freedom to go and play and express myself," Rodriguez said.
"He's said that to everyone and you can see by the way we've played that he's had a massive effect on us. Everyone knows how to play - we're pressing high and don't give anyone respect.
"The belief we've got is fantastic and we've just got to carry it on. We feel we shouldn't be where we are. We're more than good enough to beat any team and want to be higher."
