Tottenham star also congratulated Leicester City.
Spurs are fighting to now finish second in the league, with Leicester City clinching the title earlier this week.
Lamela congratulated Leicester on their achievement, which was confirmed after Spurs drew 2-2 with Leicester City.
The Argentine has showed this season he deserves to be a first team player, after a mixed opening couple of seasons at the club since signing from Roma.
He is evidently happy and committed to the cause, and will only have endeared himself to the support this week by treading on the hand of Chelsea midfielder and ex-Arsenal captain Cesc Fabregas, much to the Spaniard's complaints.
There is still work to be done this season, with games against Southampton and Newcastle to be played to ensure they finish in second place.
