Leicester City defender Robert Huth says the Premier League champions must "be man enough" to avoid relegation.
The Foxes won the title last season for the first time, but are only two points above the relegation places this term.
"We need to get on with now rather than saying: 'Last year was great,'" Huth told Football Focus. "It's reality. We are struggling with relegation."
Leicester have won only one of their eight league games since beating Manchester City 4-2 on 10 December.
They play Manchester United at home on Sunday (16:00 GMT).
"We're losing games and we can't put our fingers on how or why," added centre-back Huth.
