UEFA chief Michel Platini said here Wednesday the next few months were crucial if setbacks in developments for the Euro 2012 football championships to be held in Poland and Ukraine were to be avoided.

"I have the distinct feeling that the next four to six months will be crucial in order to avoid any critical slippage in sports and public infrastructure projects and to protect the global credibility of the Euro project itself," Platini said in a statement.

"There is a need for creating government mobilisation by making the national authorities aware of the crucial need to set up a governance and management structure to lead all the projects related to Euro 2012."

The statement was issued after a two-day meeting of UEFA's executive committee, held in the Croatian capital, which reviewed a report on progress and preparations that the two countries have made in hosting the championships.

Political instability in the two nations now seems to be over with newly-established governments taking power but there were fears that the launch of investment-intensive projects such as stadiums, airports and motorways has suffered from the instability.

In April, UEFA chose Poland and Ukraine to host the four-yearly tournament, which will bring together Europe's 16 best footballing nations.

Neither country has hosted a major championship before.
