Czech Republic manager Jaroslav Silhavy launched into a scathing rant against his side's defending as they warmed up for Euro 2020 in concerning fashion.
A 4-0 battering from Italy highlighted a number of frailties at the back with their tournament opener against Scotland at Hampden just nine days away.
Not only was the result a sore one to take but two injuries have left the boss sweating for that Group D showdown against Steve Clarke's confident team.
Silhavy likened the loss to a 5-0 thumping at the hands of England at Wembley in 2019 - and he's told his backline to get a grip or get knocked out.
He said: "It was a big setback for us, there's no getting away from it.
"It annoys me to lose by such a margin. It was a very bad performance from us and when that happens, a very bad result follows from it.
"The only good thing I can take from it was that it wasn't at the Euros.
"We were slow at everything. We lost two stupid goals. None of the defenders performed well, but it wasn't only that area, we were too slow to press and we offered nothing in attack either. The Italians were excellent, but we were nowhere near good enough.
"Additionally, we also picked up two injuries which is far from perfect. Tomas Kalas will get assessed in Prague and Ondrej Celustka also got injured. The doctors will let me know if they are available for the match against Scotland.
"The match reminded me of the debacle against England. It certainly gave me unhappy memories.
"It's behind us now, we need to learn from this, concentrate on the match against Albania and then put all our thoughts towards Scotland and ensure we don't perform like that again."
