However, every rose has its thorn and on Sunday, Alberto Moreno was that thorn.
The Spaniard was poor against Arsenal and culpable not just for giving away a penalty, but also for Theo Walcott's opening goal.
In fact, so disastrous was Moreno's performance that Sky Sports pundit Gary Neville described his performance as "absolutely garbage" in the post-match analysis and claimed: "You might as well start a goal down with [him] at left-back."
For Garth Crooks, though, a deeper-lying issue is at hand where the left-back is concerned.
According to the much-maligned pundit, relegation is a genuine possibility for the Reds so long as Moreno features this season.
He said: "Liverpool manager Jurgen Klopp is not averse to spending money if the talent is available.
"Having spent it wisely on Mane, he should seriously think about selling striker Christian Benteke - as he is surplus to requirements - and buying a decent left-back.
"If he keeps Alberto Moreno in the team, he can forget the top four - he'll get relegated."
An utterly ridiculous claim, I think you'll agree.
Crooks also named his Team of the Week, which is equally as ludicrous.
Predictably, football fans have since responded to Brooks' claims - and the reaction is pretty brutal.
The verdict is unanimous: Brooks is #clueless.
