Roberto Martinez has resigned as Portugal's head coach immediately following their 1-0 defeat to Spain in the World Cup last 16. The loss marked the end of his three-and-a-half-year tenure in charge of the national team. Martinez stepped down on the spot, confirming his departure in the aftermath of the match.

Meanwhile, England is preparing to appeal the red card shown to defender Jarell Quansah during their recent World Cup fixture. The Football Association believes the incident warrants further review and intends to formally challenge the decision through FIFA channels.
