Signed from Ipswich Town in November 1998, 'Tano' has overcome a nightmare nine-month spell on the sidelines between September last year and May to star this season.
Injury to Stephen Carr has seen the Argentinian in a right wing-back role and he has grabbed his opportunity with both hands.
Glenn Hoddle said after Monday's win against Derby County: "He's a great left or right-back in a four and we've convinced him he can play in a wing-back role as well.
"I thought he was excellent. To be honest Tano came onto a very good game probably when we went off the boil a bit and that's a credit to the player.
"It's easy when everything is in-sync and everyone's playing well but when there was a bit of anxiety creeping in he got us going again.
"His use of the ball, crossing, he got behind them a few times, nearly scored himself, it was a credit to him."
Mauricio Taricco has a signed a two-year extension to his contract to keep him at the club until 2005.
