"He was huge. He held the ball, and his work rate and what he does for the team are incredible. He is the first to set the tone and rhythm of the game," Arsenal coach Mikel Arteta told Aftonbladet.
A deep run from Gyökeres opened up Atlético Madrid's defense during the attack that ended with Bukayo Saka tapping in the rebound from Leandro Trossard's shot.
The goal was the only one of the match and Arsenal reached the CL final - the club's first in 20 years - with a 2-1 aggregate win in the doubleheader.
On Wednesday evening, it will be decided whether Bayern Munich or Paris Saint-Germain will be Arsenal's opponent in the final in Budapest on May 30.
