Much has been made of the free-flowing, pressing football introduced by the Argentinian after his arrival in January.
That tactic was effective towards the end of last season but has not quite worked so well this campaign, with only one league win to their name so far.
Saints' next opponent is West Ham and Pochettino knows exactly what they are coming up against this Sunday.
"From the three games we have seen, we can tell they are a physically strong team," the former international defender said.
"They play a very simple but very direct type of football. It is very effective for them.
"They have very good players and play in a very determined or particular way.
"That suits them so we need to prepare to suffer in certain moments of the game against them.
"But, like I always say, what we will always try to do is impose the way that we play and try to match them strength for strength."
Against such a direct team, Pochettino could be forgiven for being relieved to avoid coming up against imposing frontman Andy Carroll.
The England international has not played since completing a club-record summer move to the Upton Park club, with a foot injury this week the latest blow.
Pochettino, though, would rather be facing a West Ham side including Carroll.
"There are other players as well that bring that strength to their side," he said.
"As a manager, I am never happy when an opposing player is not able to play, when he is suffering on the sidelines.
"It is never good to see that. You always want to see the best players playing and I hope he recovers very well, very soon."
As fate would have it Rickie Lambert has arguably been the biggest beneficiary of Carroll's injury problems, making three England appearances, netting two goals.
Things are not quite so easy, though, for former strike partner Billy Sharp.
Like Lambert, he was key in Saints' promotion from the Championship but is now deemed surplus to requirements.
"The situation hasn't really changed," Pochettino said. "My position on the matter is clear.
"The club is trying to find an exit for him, a club where he can play, but the situation has not really progressed. It is the same situation."
Lee Barnard, Aaron Martin and Jonathan Forte are others the club hopes to move on, although Tadanari Lee might offer them a glimmer of hope.
Told he had no future at St Mary's, the Japan international's ability and endeavour has seen him brought back into the first-team fold.
"We had Emmanuel Mayuka leave on loan and we had one more spot to cover," Pochettino said.
"We preferred to have someone actually at the club to cover that spot than to sign another player.
"We've seen his attitude through this whole entire time. We saw his professionalism when he was playing with other players, the younger players.
"Upon seeing that, we noticed he was well deserving of a chance."
