Liverpool exacted revenge for their Capital One Cup defeat to Manchester City on Sunday by beating them 3-0 at Anfield three days later.
The Reds' performance gave fans yet another glimpse of the sort of rampant form Jurgen Klopp's side are capable of - it's just a shame they can't perform that way on a regular basis.
Victory for Liverpool came at a vital point in their season amidst their chase for a Champions League spot; they now sit just six points below fourth-placed City.

Here are five things we learned from their demolition of Manuel Pellegrini's side.
LALLANA HAS IMPORTANT ROLE TO PLAY
Having joined Liverpool for £25 million from Southampton in 2014, the general consensus amongst fans is that the Englishman hasn't yet lived up to his price tag.
However, Lallana's performance on Wednesday was a timely reminder of his undoubted ability, opening the scoring after 34 minutes and proving a constant source of creativity and energy throughout the affair.
If the 27-year-old can consistently perform as he did, there is little doubt he can become central to Liverpool's future success. Lallana's display will have also served him well with regards to this summer's European Championships.
CITY'S CHAMPIONS LEAGUE PLACE UNDER THREAT
Defeat at Anfield came as a huge blow to the Citizens' title challenge, but perhaps most importantly, their top four spot.
They still have a game in hand, of course, but the fact rivals Manchester United, alongside West Ham, Stoke City and Liverpool, are closing in gives City reason to be wary of losing out on the Champions League next season.
LIVERPOOL A FEW PLAYERS AWAY FROM GREATNESS
Klopp has already begun summer recruitment by confirming a deal for Schalke centre-back Joel Matip on a free transfer, but the upcoming transfer window provides the German with a chance to build the side he desires on Merseyside.
And if he buys well this summer, given how well his side played on Wednesday, Klopp can transform Liverpool into a side capable of competing for the Premier League. A consistent striker, new winger and centre-back should be his priority.
LIVERPOOL CAN COPE WITHOUT STURRIDGE
With the English striker renowned for his persistant injury woes, Liverpool fans have often called for their club to cut ties with Sturridge and cash in this summer.
However, the 26-year-old's impact when available is undeniable, epitomised by the goals he has scored upon his numerous returns this season.
What will have pleased fans most on Wednesday night was that Liverpool held their own even without Sturridge - but the club should by no means sell him.
CITY NEED NEW FACES
Following news that Pep Guardiola will replace Pellegrini as manager this summer, City have the opportunity to attract some of Europe's biggest names to the Etihad.
And they need to, because with their title challenge fading this campaign, it's abundantly clear their current crop of players aren't capable of dominating the Premier League to the extent of claiming the title.
