For Liverpool supporters Thursday's night's Premier League title success will live with them forever, but for Arsenal fan Piers Morgan it's a case of what could have been.
Under the shrewd managerial competence of Jurgen Klopp, the Reds' lifted their first league title in 30 years on Thursday after Manchester City's 2-1 defeat at Chelsea left them trailing by 23 points with seven games still to play.
As a result, Liverpool are now the current champions of England, Europe and the world but Morgan was left in dejection at the thought it could have been his Arsenal side tasting all the glory if they had listened to his advice five years ago.
Morgan posted a Tweet on Friday morning accompanied by three tearful emojis and a Sportsmail article from April 2015, when he urged Arsenal to sack Arsene Wenger to appoint Klopp as manager following a series of Twitter posts.
At that point Klopp was still in charge of his previous side Borussia Dortmund but had already announced his intentions to leave the German side at the end of the season, thus effectively becoming a free agent in the summer.
Already at that point Klopp was considered one of the biggest managers in Europe having landed back-to-back Bundesliga titles with Dortmund, including a league and cup double in 2012, against a vastly more resource rich Bayern Munich outfit.
The GMB presenter had said: 'Arsenal would be perfect for Jurgen Klopp - and he would be perfect for Arsenal. Sign him.
'If we don't sign Klopp, he will go to another top club and win trophies. The guy's a dynamic, driven young winner.
'Two league titles in last five years against one of the greatest Bayern sides ever - and some Arsenal fans don't think Klopp's good enough? Wow.
'Klopp would be our Mourinho. The time has come, Arsenal - act. #KloppIN'.
Despite his predictions over his future success coming true, Arsenal failed to act and stuck with Arsene Wenger for another three seasons.
Although they went on to win two additional FA Cups under the Frenchman, they also dropped out of the Champions League in 2017 and have not returned since.
The Gunners now currently sit ninth in the Premier League table with just half the points of Liverpool under new boss Mikel Arteta following the sacking earlier in the season of Wenger's eventual successor Unai Emery.
Klopp spent five months out of the game after leaving Dortmund, before being appointed Liverpool boss in 2015 following the sacking of Brendan Rodgers. The rest as they say is history.
