Tokyo 2020 men's football: Richarlison inspires Brazil, Spain held by Egypt.

Everton striker Richarlison scored a first-half hat-trick as Brazil's men began their Olympic campaign with a 4-2 victory over Germany.

In a repeat of the 2016 Olympic gold-medal match, the defending champions raced into a commanding lead despite Matheus Cunha having a penalty saved.

Richarlison scored on the rebound inside seven minutes, before heading home a second and curling in his third inside 30 minutes.

Germany put up more of a fight after the break as goals from Nadiem Amiri and Ragnar Ache made it 3-2, making it a nervous finish for Brazil.

But Bayer Leverkusen striker Paulinho finished brilliantly in injury time to make it 4-2 and put the game beyond the Germans.

Also in Group D, AC Milan midfielder Franck Kessie scored in Ivory Coast's 2-1 win over Saudi Arabia.

Earlier, Spain were held to a goalless draw by Egypt in the opening game of the men's competition despite the inclusion of Euro 2020 young player of the tournament Pedri.

A frustrating result for Spain was compounded by an ankle injury to Real Madrid's Dani Ceballos as they struggled to break Egypt down.

Ceballos had Spain's best effort, hitting the post in the first half.

Former West Brom defender Ahmed Hegazi played a key role in keeping Spain out.

Along with Pedri, there were several members of Spain's Euro 2020 squad on display, with Mikel Oyarzabal, Dani Olmo, Pau Torres and Eric Garcia all in the starting line-up.

Spain were knocked out of the Euros by champions Italy on penalties in the semi-final
