|10/1||Southampton are 10/1 with Bet365 to beat Tottenham in their next Premier League clash|
Lambert also laid on Southampton's third for Jay Rodriguez as Pochettino's side climbed above Newcastle United and back into eighth place in the Premier League thanks to the victory.
And Pochettino felt opting not to play Lambert from the start was beneficial for both the player and the team.
"As a manager I am always looking for what is best for the team and (for) every player and I thought Rickie coming on as a sub would be good for him and it was," he said.
"Sometimes tactical decisions go your way and that was the case.
"Our philosophy is always similar. We made some changes to variables to favour our attacking intent (and) I think Gaston [Ramirez] and Adam [Lallana] linked well.
"We were just looking through fresh alternatives, which we can use for the rest of a long season."
Pochettino also confirmed that a Norwich player stepped on defender Dejan Lovren's testicles during the game, explaining: "One is inflamed and swollen."
