The composition of the Tottenham attack will be one of the most intriguing aspects of Pochettino's plans for his team.
The way the wind is blowing in football these days, it is something of a rarity to see top-flight teams play two up-front.
Tottenham did last season after Tim Sherwood's appointment. Firstly with Emmanuel Adebayor and Roberto Soldado, latterly with Harry Kane replacing the Spaniard.
Pochettino's Southampton attack often featured two recognised forwards in conjunction with the creative attacking midfielder Lallana. While Rodriguez and Rickie Lambert often played together, the flexibility of the system meant it was not quite a traditional front two.
What Pochettino has in mind for the strikers he has found at Spurs will be particularly intriguing given their individual situations and how it relates to the way his team plays.
Adebayor had his issues with Villas-Boas, but he showed under Redknapp and Sherwood's management he can be a fruitful performer. With skill, strength and solid finishing, he has the attributes to play a lead role for Pochettino. He is more likely to respond given the first-choice tag than as a squad player.
Re-awakening the Soldado of his time at Getafe and Valencia will be a tempting challenge for the new boss too.
The Spaniard does not share the physically dominating presence of Adebayor. But so long as team-mates get close enough to link up with him, he hinted enough last time out at the intelligent build-up play and penalty-box nous that could make him lethal.
Kane is the dark horse to be Pochettino's main man in attack. The youngster netted three times late on in 2013-14, relishing his earned status as a central figure up top.
It would be a big call from his new head coach to hand the 20-year-old Kane the responsibility of leading the line for him, though. At his age a rotation role, or perhaps a less-demanding job out wide (where his ability to bring others into the game could fare him well) might be more suitable as he continues his development
The outside recruit option is also a possibility, of course.
