Spain got their World Cup off to the perfect start on Wednesday by hammering Costa Rica 7-0.

Ferran Torres scored in each half while further goals from Dani Olmo, Marco Asensio, Gavi, Carlos Soler and Alvaro Morata ensured Luis Enrique's side strolled to the top of Group E.

Not long after Japan surprised Germany 2-1 in the other Group E match, Spain avoided any chance of an upset with Dani Olmo, Marco Asensio and Ferran Torres scoring a goal each in the first 31 minutes. Torres, Gavi, Carlos Soler and Álvaro Morata added to the lead in the second half.

Olmo’s goal was the 100th at World Cups for Spain, which became the sixth nation to score more than 100 times in the tournament.

It was the first time Spain has scored seven goals in a World Cup match.

With 18-year-old Gavi and 19-year-old Pedri starting, Spain became the first European nation with two teenagers in the starting lineup of a World Cup match in 60 years, according to statistics platform Opta.

Gavi then became the youngest goal scorer at the World Cup since Pelé in the 1958 final, also according to Opta.
