An embarrassing late blunder gifted Paris St Germain a 1-0 home victory over Champions League debutants Girona on Wednesday as the visitors' goalkeeper Paulo Gazzaniga let a Nuno Mendes cross slip through his legs and into the net.

It took a huge blunder to gift Paris Saint-Germain victory in the first Champions League match of its post-galactico era.

There are a few things you need to know about Girona. In 1999, they were playing in the fifth tier. As recently as 2006-07, they were in Spain’s Tercera Division (which back then was the country’s fourth-highest league). Girona, the 11th-most populous city in Catalonia, is not a place known for its sporting achievements.
