Cheeky Anthony Ralston has taken a dig at the Celtic media team after a social media post left the club red faced.
The full-back has become a firm fan favourite at Parkhead after making himself a mainstay of Ange Postecgolou 's revolution.
That saw the 23-year-old called up for social media duties for a fan Q&A session in the build-up to Sunday's showdown.
However, Ralston couldn't resist answering a question on a faux pas from his own club.
Earlier this month, Celtic 's Instagram account posted a random picture of a woman eating a plate of fish. The caption read: "Sorry, I asked for the large fish!"
The post and and accompanying image were taken down within minutes but fans were quick to reply and take screengrabs of the gaffe.
That led to the following posts being bombarded about messages around the "large fish."
Back to the present day and in Ralston's Q&A one fan asked "(Do you) want a large fish?"
The Celtic defender replied: "Ask the Celtic media team - they seem to love it."
Ralston is gearing up for the crucial top of the Premiership clash on Sunday that could put his side on the brink of the title.
The Scotland cap looks likely to start with Josip Juranovic likely to be missing through injury.
