The Saints kicked on from their 14th place finish of the 2012-13 campaign, and will likely finish in the top half of the top-flight table for the first time since 2003.
Pochettino told reporters: "I think we've already achieved quite a high grade. We've already done really well throughout the entire season, taking into account all the problems that we have had on and off the pitch.
"I think that we've had a fantastic season so far. Of course it would be great to finish the season on a high note, but so far, if you analyse the season, we've been having a fantastic season."
Pochettino's side are currently eighth in the Premier League.
