"We are collating some of the experiences of the fans to get a picture of what happened," said Phil Townsend.
"We need to establish exactly what happened before we move on."
Sports minister Richard Caborn has also waded into the debate.
"I think some of the grounds are not coming up to what even Uefa are saying are the minimum standards," he told LBC NEWS 1152.
"I think one's got to be asking Uefa are they now going to be taking action with those grounds that are not coming up to the standards?
"Not a few hours before the match but weeks before the match so they go out, they look at those grounds and indeed if they're not up to standard then Uefa - by their own code - ought to be taking action.
"Now I think it's up to Uefa to make sure they do carry out inspections and those inspections are acted upon if they are substandard."
