Lamela, 22, joined Tottenham from Roma in August 2013 for a club-record £25.8 million as part of the rebuilding effort that followed Gareth Bale’s £85.3 million departure to Real Madrid.
The Argentina international failed to perform up to expectations during his debut campaign at White Hart Lane, however, registering just one assist in nine Premier League games under Andre Villas-Boas, before a back problem saw him ruled out for much of Tim Sherwood’s tenure.
A potential summer departure was mooted, but the subsequent arrival of Pochettino has since seen the former River Plate product start to fulfil his promise, having grabbed four goals and seven assists in 31 total appearances so far this season.
With the team getting over a slow start to climb up to within one-point of fourth-place Manchester United following the weekend’s 2-1 home win over Arsenal, Lamela believes the squad are now starting to reap the long-term benefits of his fellow Argentine’s disciplined approach on the training ground.
"Maybe it was my fault at some point but I never had the training sessions to do it better,” he said. “There was a lack of training to [help me get] fit. This year, the sessions are helping me a lot and obviously [there is] the continuity of the games too.
"There has been a big change from last season. I started last season without playing and never had the chance to do it.
"The hard training sessions eventually make the difference in the long term. On the ground you can appreciate when a team is well-worked and you see it against Arsenal. We hope to keep the run and keep improving. We cannot relax.”
Lamela’s performances have been much-improved in recent months compared to last season but, having managed 15 goals during his final campaign in the Italian capital, he admits that is still to show Spurs fans his worth.
"I think I can give much more,” he added “This year I'm happy but I want to score more goals, provide more assists... I have to be ambitious. Obviously, I can give much more."
