The only thing with that site is that it doesn’t count wins/defeats on penalties as wins/defeats, it counts them as draws.
Last season we lost to Arsenal (Community Shield) and Real Madrid (Champions League) on penalties and, for me, they should be true defeats… we didn’t share the CS on Saturday with United, we won it!.
So it says on there that last season (2023-24) we only lost 5 games. That would be our record according to that site, but we actually lost 7 games.
That site also counts our 2016 EFL Cup win on penalties against Liverpool as a draw, 2019 EFL Cup win on penalties against Chelsea as a draw, the 2020 CS win on penalties against Liverpool as a draw and the 2023 UEFA Super Cup win on penalties against Sevilla as a draw.
