Juan Foyth represented something resembling an enigma just a few weeks ago, but he has rapidly established himself as an important part of Mauricio Pochettino's first-team squad in little over three weeks. 

The extent of Foyth's ability was based purely off a handful of domestic cup performances and hearsay prior to his Premier League debut against Wolves at the start of the month. Fast forward three and a half weeks and Tottenham supporters are markedly more aware of what the 20-year-old central defender can offer.

Playing with the exuberance and eagerness to impress of a young lion cub, who is simply craving the validation and affection of its mother, Foyth has certainly raised some talking points in recent weeks.

In Foyth's case, he has been seeking the love of the Lilywhites faithful on the terraces, his richly gifted teammates and, of course, his compatriot patrolling the dugout, Pochettino.

The effects of his first full ninety minutes of intense Premier League football took their toll on Foyth against Wolves, as he twice stuck out a clumsy leg to give away two penalties which, fortunately for his budding reputation, did not prevent Spurs from taking all three points.

Against Palace he turned from zero to hero by showcasing lightning quick reactions, which Harry Kane would be proud of, to head home the only goal of the game, before he faced his biggest test in professional football against Chelsea.

Perhaps Foyth should have made it three penalties conceded in three games when he upended Eden Hazard last time out, but Martin Atkinson gave him the benefit of the doubt, and he now finds himself due for a rest against Inter Milan due to his ineligibility.

Foyth was not included in Pochetitno's Champions League squad at the beginning of the season, but he has since admitted that the Argentine's absence is regretful (as per Sky Sports).

"At the start of the season I was disappointed because the squad was so big. People say, 'You were the only club not to sign any players'.

"But to sign another player means to put another off the Champions League list. We needed an English player but it was impossible.

"It is painful to have a player off the list but we will finish [the group stage] soon and hope that in March we can do a new list and we can include him on it.

That Pochettino is already revealing his intention to include Foyth within his European squad in March - should Spurs qualify for the knockout phase of the competition - is indicative of how rapidly he has established himself this season.

Just a few weeks ago his future was in question, with speculation regarding Pochettino's disappointment over Foyth's lack of development hinting at a January departure, but the dynamic is incomparable now.

What a difference a few weeks makes. Foyth is here to stay and, if Spurs can record two massive victories in Europe, starting tonight against Inter Milan, he could make his Champions League debut by the end of the season.
