Southampton produced a classic FA Cup upset, knocking out Premier League leaders Arsenal with a 2-1 win in the quarterfinals at St Mary’s yesterday. Ross Stewart gave the hosts a 35th-minute lead before Viktor Gyokeres equalised midway through the second half, with Mikel Arteta’s side looking the likelier winners. But a late counter on 85 minutes saw Shea Charles strike to seal a memorable giant-killing. Wearing a special yellow kit to mark 50 years since their 1976 FA Cup triumph over Manchester United, Southampton advanced to the semis alongside Manchester City and Chelsea. The defeat, following their EFL Cup final loss to City, leaves Arsenal’s quadruple hopes over, with only the Premier League and Champions League remaining.
