Clarke, who is now a well-known analyst, has spoken highly of the Argentina international’s work rate and professionalism.
“Although best known for his skill, the 23-year-old has bought into Mauricio Pochettino's high-intensity demands better than most, and as a consequence he is virtually unrecognisable from the 'luxury' attacker who arrived from AS Roma in August 2013,” the Englishman wrote on Premierleague.com.
“When Spurs go hunting for the ball, pressing opponents with ferocity, Lamela is now at the forefront of that 'dirty work', covering vast expanses of ground at speed to unsettle rival teams.”
Lamela has been on the books of Tottenham since 2013, but it is this season that he is playing close to his best.
The Argentina international, who can play as a winger or as an attacking midfielder, has scored three goals and created 45 chances in 23 Premier League appearances for Spurs so far this campaign.
The 23-year-old has a pass accuracy of 79% and a shot accuracy of 54%, and has won six headers, 29 dribbles and 33 tackles.
Tottenham are second in the Premier League table at the moment with 51 points from 26 matches, just two points behind leaders Leicester City.
The North London outfit will return to action on Sunday afternoon when they take on Crystal Palace at White Hart Lane in the fifth round of the FA Cup.
