The proposed 60,000-capacity Eurostadium in Grimbergen, north of Brussels, is due to stage matches but is yet to be built.

A meeting has taken place between the national and continental federations plus local lawmakers and constructors.

UEFA will now make a final decision on December 7.

The decision is likely to depend on whether Belgian officials can prove that they have all necessary permits to begin stadium construction by November 20.

"We still believe, but we are realistic that it's depending on other parties," Royal Belgium Football Association secretary general Koen de Brabander said during the UEFA meeting.

"We as a Federation are not in the lead to take decisions.

"It's not our role to invest in concrete, and we don't have the money for that."

The Football Association of Wales has already reacted positively after originally missing out on the opportunity to host games.

"We will work hard to once again produce a strong case for the games to be played in Cardiff and will use the experience of the Champions League to demonstrate what a success we will make of hosting these matches," said chief executive Jonathan Ford.

"It would be fantastic for Welsh football to not only qualify for the Euro 2020 finals but also to stage some of the key matches."

Cardiff's Millennium Stadium has already been tested by UEFA when it hosted the Champions League final in June.

Thirteen stadiums across 13 countries are due to host matches during the 24-team event.

The final has been awarded to Wembley Stadium in London.

London and Swedish capital Stockholm are other contenders to step-in if Brussels loses its hosting rights.
