Spurs now look well covered in central midfield thanks to the Argentine's influence.
Discontent over Tottenham Hotspur’s summer transfer window going into the season boiled down to two main areas which many felt were under-strength – up front and central midfield.
The striker situation is proving something of an issue, with Harry Kane’s stuttering form - and no direct alternative to him - partly responsible for Spurs’ meagre goal return (the lowest out of the top nine clubs, with 11 goals).
But there are no such issues in the heart of midfield, and Mauricio Pochettino must take credit for that.
Spurs were linked with several central midfielders over the summer and the consensus was that a true defensive-minded figure was required to balance the attacking tendencies of the rest of the midfield.
Pochettino’s first masterstroke was the conversion of Eric Dier from centre-back to midfield destroyer – the success of which no one could have predicted.
The 21-year old has been one of the standout midfielders in the Premier League this season and it’s testament to Pochettino’s conviction in his philosophy and trust in his young players, that he was willing to throw him in at the proverbial deep end.
It’s a similar story as far as Dele Alli is concerned and Pochettino’s faith in the 19-year old has meant he has played a far bigger role than anyone would have expected so soon in his Spurs career.
The former MK Dons man has real star quality and has looked adept in a deeper box-to-box role or as one of the interchanging attacking three behind the striker.
Pochettino’s willingness to place his trust in youth has provided the Lilywhites with two central midfield options who would not have been considered first-team solutions just a few months ago.
He did the same with Ryan Mason last season and with the Spurs academy graduate due for an imminent return - alongside Nabil Bentaleb and the resurgent Moussa Dembele – Spurs have nothing to worry about as far as their central midfield prospects go.
