An eight-year-old boy was left in floods of tears after a trip to watch his beloved Liverpool turned into the "worst day of his life".
What started out as a day full of excitement ended in heartbreak as football mad Campbell Kaplinsky was denied the chance to watch Jurgen Klopp's Reds for the very first time.
The Liverpool lover's wish had been granted when his dad secured tickets to watch the Anfield outfit take on in-form West Ham at the London Stadium on Sunday.
However, eight-year-old Campbell missed the Premier League thriller, which saw the Hammers run out 3-2 winners and dramatically end Liverpool's 25-match unbeaten streak, after being refused entry.
Reds' stopper Alisson clumsily punched the ball into his own net to put West Ham ahead early on before a sumptuous Trent Alexander-Arnold free-kick levelled the match shortly before half time.
Goals from Pablo Fornals and Kurt Zouma then put David Moyes' high-flying Hammers into a commanding lead before substitute Divock Origi pulled one back for Liverpool late on.
If the result wasn't heartbreak enough for any Liverpool fan, missing out on watching Mohamed Salah and co in the flesh only compounded the misery for young Kaplinsky.
After dad Ben had snapped up the tickets as a reward for his son going to bed on time three weeks in a row, Campbell was refused entry to the London Stadium after the pair were discovered to be sitting in the home end.
Gate officials explained to the father and distraught son that club policy states away fans are not permitted in any West Ham sections as they were forced to turn the Liverpool-supporting pair away.
Speaking to the Liverpool ECHO, Ben said: "He was so excited he wanted to arrive at the train station more than 30 minutes before the train arrived.

"He woke up at 6.30am full of excitement and spoke about nothing but the match all day."
The pair's two-and-a-half-hour journey from Brighton to West Ham's London Stadium was all in vain however, as the long-awaited trip took a disastrous turn.
"The poor boy was inconsolable, locked out the stadium as the best day of his life turned into the worst day of his life," his dad continued.
"As he went to sleep that night sobbing, I did my best to comfort him by reminding him of that timeless Liverpool anthem of strength, hope and resilience - 'though your dreams be tossed and blown at the end of the storm there is a golden sky and you will never walk alone'."
Despite young Campbell's Liverpool shirt being concealed under a camo jacket, West Ham clearly state that home match tickets are for the use by West Ham supporters only.
With his precious Liverpool having suffered defeat, Campbell's day may well have been destined to end in tears either way.
