The beloved Reds fan guessed his side would win 5-0, and that’s exactly what happened at Old Trafford.
The Irishman appeared at the Los Angeles coliseum along with fellow grappler Drew McIntyre to promote American network NBC’s coverage of the mega matchup.
Sporting Liverpool’s away top, Sheamus and McIntyre, who was supporting United, shared some banter ahead of the game.
Passionate as ever, the 43-year-old yelled: “Let me explain something to you fella, you guys are going down today.
“Liverpool are going to take the three points and we’re going to go on to win the Premier League!”
He added: “We’re going to stuff these guys 5-0 today!”, before McIntyre retorted: “Not a bloody chance!”
The Scot would be made to eat his words as Liverpool opened the scoring early on through Naby Keita, before Diogo Jota doubled the lead less than ten minutes later.
The 2020 League champions were only just getting started, as they cut through United’s defence at will.
Seven minutes before half time, Mo Salah continued his fine scoring run, turning in Keita’s low cross from close range.
The Egyptian doubled his tally in first time half stoppage time, making it 4-0 to Liverpool and this marked the first time United trailed 4-0 at the halfway stage in the Premier League.
Soon after the break Salah would become the first Premier League player and just the second overall to score a hat-trick at Old Trafford, coolly slotting home after a delightful ball by Reds skipper Jordan Henderson.
Following the match, Sheamus posted a snap with McIntyre on Instagram and poked fun at him following the result.
He penned: “Savage time at #mypremierleaguemorning Cheers @nbcsportssoccer for having us. Still can’t find @dmcintyrewwe though.”
Both wrestlers, who are former WWE champions, were drafted to SmackDown from Raw earlier this month and will be looking to hit the ground running on the Friday night show
