Rangers chief executive Charles Green has taken another swipe at Dundee United ahead of the Scottish Cup tie between the teams in February.
Green refused to take tickets for the match, with the backing of first-team boss All McCoist, after a section of his club's supporters suggested a boycott of the fixture.
But United have decided to sell tickets to fans of the Third Division club after the Scottish Football Association clarified they would still have to split the gate money 50/50 with Rangers.
Green now believes there could be trouble among the away fans at Tannadice, and is calling for United to change the decision.
"We have been very clear from day one, because of the fans' issues with Dundee United in the past as a board we made the decision not to take tickets and requested they didn't make tickets available to Rangers fans," Green said.
"There are a number of issues, safety has to be paramount. We are very conscious of safety. We are concerned that Dundee United won't know who they are selling tickets to and how will they know if they're genuine Rangers fans or potential troublemakers?
"Ally supported this and was part of the decision-making process. Who better as a former player, a fan and a manager who said that fans shouldn't go to the game.
"I would ask United to think again. The majority of Rangers fans said they didn't want to go. There will be a few who do and I can understand that."
Clark, who has skippered Villa in recent matches, started Ireland's friendly international with Greece last month.
He is still eligible to play for England whom he represented at under-17 and under-18 level, as he has not played in a competitive match for Giovanni Trappatoni's team.
But Clark is still determined to play for the country of the birth of his parents.
He said: "It was nice to get the game last time, a friendly. All I can do is keep trying to play well here at Villa and hopefully I'll be in the back of their minds with Ireland.
"Wes Hoolahan was in as well against Greece and a couple of other lads were picked as well. It does give the other players hope now they might get a chance in the up and coming fixtures.
"I was regular for England Under-17, Under-18s, at the start of my career, but it's moved on now.
"I know there are a couple of friendly internationals leading up to the World Cup qualifiers and I've got to see what happens with that.
"Would I go back to England? No chance of that, not at all."
Clark, 23, has relished being Villa captain in the absence of the injured Ron Vlaar and admits skippering several of the players at youth level has made the role easier.
He said: "At the start of the season I never imagined I would be captain now. When a new manager comes in, you just want to try to get a place in the team first and foremost.
"That was my only goal and I've managed to play a number of games which has been a massive bonus for me.
"I captained at reserve and youth-team levels. I am vocal on the pitch. I do like to bark the orders out. It is just passing on info really, getting everyone communicating.
"It is maybe easier to communicate with lads you've played with for a while. The older lads are a lot more experienced and know what they should be doing anyway."
Current first-team players such as Clark, Nathan Baker and Chris Herd all graduated through the academy ranks at Villa.
Clark said: "It is good because we've come through the youth team, even younger than that, right through since the under-18s and reserves.
"We've won youth team and reserve leagues so we are all good mates and all know each other's games really well so that can only be good."
