Lallana is closing in on a return to action following a six-week knee injury layoff.
Much has changed since the Saints skipper suffered the injury against Reading last month.
The club have moved out of the Barclays Premier League relegation zone and they also have a new manager in Pochettino, who was installed following the shock dismissal of Nigel Adkins last week.
Lallana, speaking in Barcelona where Southampton are enjoying a warm-weather training camp, watched his team-mates batter Everton before emerging with a point on Monday in Pochettino's first game in charge and he is sure the future is bright for the club under the former Espanyol boss.
"You saw what style of football he wants us to play on Monday night - the lads came flying out of the traps and were pressing hard," the 24-year-old told Southampton's website.
"It's going to be different, but it's going to be good.
"The lads have done absolutely brilliantly over the Christmas period, and the game on Monday was outstanding - the first half was probably the best I've seen all season from the stands.
"I'm so eager to get back playing, especially under the new boss. There's a team of four who have come in, and the gaffer is starting to get his messages across.
"We've come here for four days so he'll start to tactically put his imprint on how he wants us to play."
