Unlike his World-Cup winning father, who made more than 1,000 professional appearances during a glittering career as a goalkeeper before retiring in 2023 – the 17-year-old is a left-sided attacking player.

Forward Louis was introduced as a late substitute by Pisa boss Filippo Inzaghi – who played alongside his dad for the Azzurri – as they fell to a 3-2 defeat at Spezia.

Turin-born Louis recently elected to represent the Czech Republic, where his mother is from, at under-18 level.
