Goalkeeper arrested for conceding 43 goals

I'm just confused. How do you concede 43 goals?

Should the “offence” be excusable because the goalie is an amateur?

Here’s the scoop. Goal keeper, Marco Kwiotek was picked up by the police during a training session after his side, SV Vonderort lost to PSV Oberhausen. The German team consisting of refugees from Syria, Iraq and Guinea made headlines after they were heavily walloped by their opponent.

According to the report, shortly before the end of the session, policemen approached the goalie and whisked him away for questioning. He was released almost immediately after.

Imagine a PL or La Liga team conceding 43 goals?
