Leeds United fans were quick to spot Marcelo Bielsa exploding in celebration after Stuart Dallas' goal during Tuesday's 3-0 win over Southampton.
Leeds had lost their last two matches, both of which featured the absence of Kalvin Phillips.
Their first-half performance against Arsenal was one of the more underwhelming 45 minutes of the entire season, while their 1-0 defeat to Wolves was also damaging to their hopes of a top-half finish.
However, in continuing their tradition of an up and down season - their first back in the top flight - Leeds turned their recent struggles on their head once again.
Patrick Bamford opened the scoring against Southampton, before Stuart Dallas and Raphinha took the game away from the Saints to seal a comfortable 3-0 win by full-time.
And it was Bielsa's reaction to Dallas' strike that caught the attention of Leeds fans.
As a part of Dugout Cam, in which Leeds showed video footage of the dugout's reaction to events on the pitch, Bielsa could be seen exploding into life after Dallas prodded a brilliant left-footed finish into the bottom corner from just inside the penalty area.
A scintillating Leeds break saw those around Bielsa grow in excitement at the prospect of a goal. Bielsa remained calm, until Dallas found the bottom corner, producing a double-fist-pump as he joyously reacted to Leeds doubling their victory and all but securing the victory.
Leeds fans were ecstatic with Bielsa's roar of passion.
In reply to a video of the moment on Twitter, one fan said: "Great emotion, but watch the rest of the squad behind.. everybody focused and celebrating like the fans would!!"
Another added: "Bielsa has a passion for Leeds United its clear to see."
Andy Tunstall then summed up almost every Leeds fans' love for Bielsa: "Watched this 19 billion times love the man."
On the excellent second-half performance, Bielsa said in his post-match press conference: "In the second half, having been able to score so quickly, it opens up the game.
"The difference of three goals is bigger than the difference in the performance between the two teams.
"We had to put in a big effort to not allow them to dominate and dominate in the moments which we did."
