Liverpool's Portuguese forward Diogo Jota was probably speeding when the Lamborghini car he was driving crashed in northwestern Spain, killing him and his brother, police said in a preliminary report on Tuesday.

Diogo Jota, the Liverpool star who died along with his brother in a car crash last week, was traveling over the speed limit, authorities in Spain said Tuesday. The Spanish Civil Guard’s investigation is still ongoing, but they said their belief is that Jota was driving too fast in his Lamborghini before a tire burst, forcing the car off-course.

Police believe Diogo Jota, a Liverpool and Portugal star striker, may have been driving over the speed limit, which contributed to the fatal car crash that claimed the lives of him and his brother last week.
