Since Diego Simeone returned to Atlético de Madrid as coach, 87 different players have represented Los Colchoneros in Madrid derby matches across all competitions, with Gabi the veteran of clashes with Real Madrid.
The Spanish midfielder has played in every single match against Los Blancos since the Argentine's appointment and knows better than anyone what it takes to succeed in such encounters.
Simeone has brought such change to the footballing landscape in the Spanish capital, it is difficult to remember what things were like before.
Real Madrid were a far superior team and would regularly defeat their rivals with ease.
Gabi has seen the battling spirit that the former River Plate coach has brought and no player embodies it more than the club's captain.
Not only is he a leader on the pitch, he guides Los Rojiblancos in all areas and is the emblem for the club in the modern era.
He was present for the first three derby matches of the current era; three successive defeats for Atleti which many feared would continue.
May 2013 saw Los Rojiblancos defeat their fiercest rivals in the Copa del Rey final and it was the 34-year-old who hoisted the trophy aloft.
After having been a ball-boy for the club in his youth, Gabi lived the dream as he captained the club to multiple victories over Real.
Such has been the team's dismal start to the current campaign that a derby victory is now incredibly important. Victory could galvanise the hosts and catapult them back into the title race.
After having been present in the dark periods before Simeone's arrival, it falls on Gabi's shoulders to motivate the players around him and carry the team forward in the first ever Madrid derby at the Estadio Wanda Metropolitano.
