Reports have suggested that infrastructure problems could lead to the event being relocated.

Platini, who will visit both countries in the coming weeks, has refused to confirm or deny such rumours.

"I don't want to talk about that during the European Championship," he said. "But I'm going there on July 2 to take stock of the situation.

"I know that certain people are already talking about the possibility of giving the competition to another country, which could be Spain.

"At the present moment however, that's an unfounded rumour."

The threat that the tournament could be played elsewhere is a very real one, with roads, airports and rail networks in both countries needing heavy modernisation, as well as the stadiums.

The renovation of Kiev'sOlympic Stadium, which will host the final, is already massively behind schedule with the contractors for the task now set to be decided on only days before UEFA's visit.

Meanwhile, Platini also revealed that in future the European Championship could take place at the beginning of the season to combat player burn-out.

"I have already talked about the possibility of playing the Euros a bit later in the year, in August, after the players' holidays, when they will be more fresh," the Frenchman said.

"But we have to come to an agreement with the clubs and come up with a new calendar.

"I am sure the clubs would then say that their players were rejoining them tired... we have to study it.

"Russia's good form hasn't surprised me because we knew they would arrive very fresh at a physical level as almost all their players ply their trade in their league which has only just started."

Plans to expand the tournament from its current 16 teams, to possibly as many as 24, will also soon be considered.

"We're talking about it here in Vienna," he added. "But we'll study it in September in Bordeaux.

"There we will make a decision after hearing all the opinions and if we expand it it won't take place until Euro 2016."
