Spanish giants Real Madrid CF and FC Barcelona could face game cancellations this weekend. The two teams’ games along with other Spanish La Liga fixtures are under threat of being postponed if the European heat wave does not abate. Rising temperatures in Spain have been deemed dangerous for the players.

Spanish Football League President Javier Tebas has announced that La Liga fixtures this weekend may be postponed because temperatures have been reaching 40 degrees Celsius in the past several days. According to the Daily Mail, Tebas believes that the extreme heat poses a threat to the players, especially those whose matches are scheduled in the afternoon.

Real Madrid is scheduled to host Osasuna at the Santiago Bernabeu Stadium on Saturday. Kick-off has been set at 4:00 pm. Scorching temperatures in the Spanish capital could prove to be a major challenge though. Meanwhile, Atletico Madrid also has a match scheduled against Celta Vigo in the same afternoon. Their kick-off time is set at 1:00 pm, the height of the sun’s wrath.

FC Barcelona may have cooler temperatures during their match, which is scheduled at 8:30 in the evening. Nevertheless, if temperatures hover around the 36 to 38 degree mark, matches might still have to be postponed. At the very least, multiple cooling breaks could be imposed.

Moving afternoon matches later in the day is a possibility. However, recent weeks have proven that soaring temperatures do not get significantly milder in the evening. It remains to be seen if some drastic scheduling changes will be finalized. In the 2014 World Cup in Brazil, cooling breaks were imposed in order to help players cope with the extreme tropical conditions.

”You cannot play a game of football with temperatures of 36, 37 or 38 degrees. We have discussed the heat issue, not just because of this weekend but because of the previous rounds,” said Tebas.
