Alisson Becker scored his legendary goal against West Bromwich Albion on this day in 2021.

If anything, it's crazy to think that only a year has passed between Liverpool scrambling for a place in the top four and challenging to win the top four trophies available to them.

Nevertheless, there are many Kopites who would understandably point towards Alisson's header at the Hawthorns as the moment that set the wheels in motion for a potential quadruple.

Happy birthday, Alisson's goals

If it wasn't for Alisson's dramatic winner against the Baggies, there's good reason to think that Liverpool simply wouldn't be playing in the Champions League this season.

And a world in which that sweet, sweet anthem wasn't echoing around Anfield across the 2022/23 campaign is one in which winning the quadruple simply wouldn't be possible.

Now, sure, there was more behind Liverpool's third-place finish last season than just Alisson's heroics, but there's no denying that it served as a massive morale boost in their Champions League quest.

As such, Jurgen Klopp's men will have to thank Alisson for more than just his stunning performances this term if they do indeed become the first English club to win the quadruple.

But even if the Premier League and Champions League trophies wind up in Manchester City and Real Madrid's hands, it will do nothing to take the shine off such an emotional moment.

Alisson relives his iconic winner

Besides, it's not everyday that you can say your goalkeeper scored a last-gasp winner in the Premier League even if you ignore the entire top four race and subsequent quadruple narrative.

In fact, such was the sheer joy of Alisson's goal in isolation that Liverpool couldn't help raising a glass to its first anniversary by getting the man himself to react to his stunning finish.

As part of the club's "Alternative Commentary" series, Alisson sat down alongside FA Cup hero Kostas Tsimikas to watch back Liverpool's 2-1 win against West Brom as faux broadcasters.

And if you know anything about the incredible team spirit amongst this Liverpool squad, then you can already picture just how amusing and entertaining it is to see their commentary impressions.

By the time everything culminates in Alisson's unforgettable goal, the video truly tips over the wholesome-o-meter and makes for a joy to watch that you can check out for yourself below (skip to 3:30 for the winner):

You love to see it.

Wholesome scenes

As much as we love the 'Greek Scouser' chat and jokes about Mohamed Salah's hair, it doesn't get much better than Alisson and Tsimikas losing their minds at the sight of Liverpool's late winner.

Tsimikas definitely deserves full marks for his commentary that spills over into picking up one of the Quorn products and heading it just as emphatically as Alisson's goal against the Baggies.

And while it might ultimately be just a bit of fun for Liverpool's social channels, you don't need to be a body language expert to identify just how well the two Reds stars get along with each other.

One can't help feeling that the enviable team atmosphere that Klopp has established at Anfield is a massive reason behind special moments like Alisson's winner coming to pass for the Reds.

Mentality monsters indeed.
