The attacker has established himself as one of Pochettino's key men.
The 24-year old enjoyed his best season for Spurs last term and is now a firm favourite among fans after a difficult start to life at White Hart Lane.
"I think Erik has matured a lot," said Pochettino. “Today, he’s a different player to the day we arrived (at Spurs). Always, young players need time and different players sometimes need more time.
"Erik has good qualities, a big heart, works a lot and his season was fantastic."
Lamela arrived from Roma in the summer of 2013 as part of the post-Gareth Bale spending spree and suffered a miserable debut campaign that was cut short by injury.
He improved during the following season - clearly benefiting from Pochettino’s arrival - and his transformation was complete last term.
The Argentine’s willingness to hunt down the opposition and his consistent provision of assists has made him a mainstay in this new-look Spurs team, and judging by Pochettino’s comments, his hard work does not go unnoticed.
Spurs have been linked with attacking additions such as Michy Batshuayi and Franco Vazquez – by the likes of the Mirror and Sky Sports respectively– and Lamela may find his starting position under threat should Hotspur Way see some new arrivals.
Of Tottenham’s attacking four – Lamela, Kane, Eriksen and Alli – it is the Argentine that will be most under threat should a new talent arrive, yet his mentality when times were tough at the Lane suggests he will not go down without a fight.
