It’s no surprise that The Celtic Warrior is a supporter of Celtic football. Therefore, with unbeaten Celtic F.C. already enjoying its sixteenth Scottish League Cup and sixth straight Scottish Premiership title, Sheamus hopes the team will be celebrating its achievement of capturing the much-desired-but-nigh-unattainable domestic Treble (winning three championships in a single season or calendar year) when WWE’s Superstars officially kick off WWE Live’s tour through the U.K., starting  in Glasgow’s SSE Hydro Thursday, 4 May.

Sheamus has never been shy about professing his love for the world’s most popular sport or for two of his favorite teams (the other being Liverpool F.C.). Additionally, visiting the Celts' Lennoxtown training complex last year remains a personal highlight for the first-ever Irish-born WWE and World Heavyweight Champion. Hence, the prospect of Celtic earning its fourth Treble in the team’s proud 130-year history prompted him to don the green-and-white hoops and send out a special video message to "The Bhoys." (A message that includes a special appearance from a certain Swiss Superman – and Rangers F.C. supporter – who wouldn’t mind seeing Celtic’s Treble dreams dashed by a Scottish Cup semi-final loss to Rangers this Sunday.)

Message received, Sheamus, and shared by Celtic's social platforms:

💪 @WWE superstar @WWESheamus knows what it means to wear the Hoops.

Without meaning to sound biased, we’re hoping the Celts come through. And even though Sheamus isn’t part of the SmackDown LIVE roster for WWE Live’s visit to Glasgow 4 May, you can be certain that he’ll enjoy seeing his Bhoys bask in championship glory – and perhaps share in some of his own should he and tag partner Cesaro beat The Hardy Boyz for the Raw Tag Team Titles at WWE Payback Sunday, April 30.
