Otamendi scored an important goal for Valencia over the weekend, whilst also demonstrating his superb defending credentials.
It all goes down to the final game of the campaign in La Liga, when it comes to Valencia securing their objective of playing in the Champions League next season.
In a somewhat disappointing result, Valencia were held to a 1-1 draw at the Mestalla against Celta Vigo. Meanwhile, nearest rivals Sevilla edged to a 2-1 victory against Almeria.
Valencia must now win their final game of the season away at Almeria, whilst hoping they slip up again, Sevilla will need all three points away at local rivals Malaga, given just a point splits the two sides in fourth and fifth respectively.
The saviour of a point on Sunday for Valencia, was central defender Nicolas Otamendi, who scored the crucial equalising goal against visiting Celta Vigo.
A former Argentina international and centre-back himself, Celta boss Eduardo 'Toto' Berizzo knows a thing or two about what makes a top player, especially for his own country.
"He's a player with huge physical presence, one that covers the whole pitch with his defensive instincts, plus the right touch of aggression, which makes him a fantastic defender."
Clear that Otamendi is by far the best of his generation, Berizzo further eulogised the quality of the 27-year-old Valencia man, and without any doubts added: "Not only can he defend, but he has the ability to unlock difficult games. For sure, he's one of the greatest Argentine defenders of all time, and of course, in La Liga."
Along with his exceptional defending, Otamendi scoring a fifth goal of the campaign achieved a club record for Valencia, as the highest scoring central defender in a season for Los Che.
Argentina will be hoping his stellar form continues, with Otamendi being a key part of their assault on the Copa Ameria this summer.
