England midfielder Jude Bellingham has sent a warning to his teammates ahead of their European Championship last 16 tie against Slovakia.
The Three Lions finished top of Group C but only managed one and back-to-back draws in their three games over the past two weeks.
Bellingham did received a bulk of the criticism after the goalless draw against Slovenia on Tuesday evening, with many feeling he is not replicating his Real Madrid form for the national side.

England avoided the big guns by finishing top but the midfielder insists Slovakia will be no pushovers.
"I think people look at the draw and see Slovakia and think it will be an easy game," Bellingham told England's in-house "Lions Den" broadcast.
"It definitely is not the case because they will be a different type of threat and will be difficult to break down.
"I think when you play nations who come at you a bit more, it's a lot more open.
"I think that you're always going to have tough games at this point in the tournament," Bellingham added.
