The Argentinian went into the clash with Leicester on Tuesday night still awaiting his first appearance for Mauricio Pochettino's side since their EFL Cup defeat to Liverpool in October 2016 - and began the game on the bench at the King Power Stadium.
He did get onto the pitch 13 minutes from time and made an immediate impact for Tottenham, providing the pass that allowed Harry Kane to give Spurs a glimmer of hope by making the score 2-1 to Leicester with 11 minutes to go.
And while Lamela expressed his disappointment as the team failed to find the equaliser in the remaining minutes, he also admitted how great it was to be back playing after more than a year on the sidelines.
"I fought every day to be good, to train, to help my team-mates. I did my best always and that’s why, today, I’m here again. Today is another step. I am back on the pitch and it felt amazing to play again in front of the people but unfortunately we didn’t win."
With Tottenham currently enduring a fairly miserable run of form, it will undoubtedly be a major boost for Pochettino to have the 25-year-old back in the ranks as, when he is on form, he has the quality to make an impact, as he proved on Tuesday.
If nothing else, his return should arguably help bring the best out of the other attacking players within the Spurs squad as they will know that they have another rival for their position who has already shown what the side were missing with a neat pass for Kane to smash home Tottenham's goal.
