Cristiano Ronaldo’s sister, Kata Aveiro, has described the just-concluded FIFA World Cup in Qatar as the worst of its kind.

However, Kata congratulated the World Cup winners, Argentina, and their main man, Lionel Messi.

Argentina beat France 4-2 on penalties to clinch the most coveted trophy in world football on Sunday.

The game ended 3-3 after 120 minutes and was decided by a penalty shootout, which Messi and his colleagues comfortably won.

“The worst World Cup of all time… that thankfully gave us a great final. "What a match,” she wrote on Instagram.

“Congratulations to Argentina.”
