St Johnstone have called comments which Neil Lennon made regarding the club's McDiarmid Park facilities "completely inaccurate and unfounded".
During a press conference on Monday where he railed against criticism of his club for their team trip to Dubai, Lennon claimed that Celtic are being held to higher standards than other sides in Scotland.
"Show me anyone who is doing the right things," said Lennon.
"When we played Hibs we had to bus six players in two buses because we were told now that is the way it has to be. Three people on a 52 seater bus. That has not been going on throughout the season.
"We have been going to away grounds where we are cramped in like sardines. Boxing Day at Hamilton there was no social distancing there, there was no physical distancing.
"It is inconsistent. Protocols of different clubs are inconsistent. We go to St Johnstone all crammed into a little dressing room. Inconsistent.
"As soon as Celtic are deemed to do something wrong then bang. You are all wanting blood. It is absolutely scandalous."
In a statement issued on Tuesday, St Johnstone rejected Lennon's claims.
"St. Johnstone Football Club is extremely disappointed with the completely inaccurate and unfounded comments about our facilities made yesterday by Neil Lennon, the Celtic FC manager, in a media conference.
"We provide one of the largest away team changing areas in the league. Every team, including Celtic, is also provided with a large area for team meetings.
"We follow all protocols and guidance to ensure the health and safety of all players, staff and officials.
"When Celtic FC visited McDiarmid Park on October 4th for an SPFL Premiership match, we made sure their every request and requirement was met. Celtic viewed all of our facilities before the game and no issues were raised. No issues were raised with us after the game.
"All during this challenging period of the past nine months, our Football Club has maintained adherence to the highest of standards. Indeed, the SPFL delegates have commended us on our work during this campaign."
