The Blancos have seen a positive opening to the 2018-19 campaign snapped by an alarming wobble over recent weeks.
A four-match winless run has seen the Santiago Bernabeu giants drop precious points in La Liga and the Champions League.
While that sorry sequence of results is an obvious problem, an inability to net any goals during it is of greater concern.
The international break offers some respite for Real, with domestic action taking a breather.
Kroos remains confident that the Blancos will come good, with past experience having taught them how to handle tough times.
He posted on Twitter: “Two weeks of disappointing results, games and also bad luck.
“We deserved more points because we didn‘t play that bad - but it is what it is.
“Don’t forget we also had these moments in the past three years... Will be a great challenge to stand up again! Hala Madrid!”

Madrid have come through testing periods in recent seasons to remain in the hunt for major silverware.
A hat-trick of Champions League crowns have been secured, while Zinedine Zidane also oversaw La Liga, Super Cup and Club World Cup triumphs before stepping down from his post over the summer.
Real still have plenty of time to work their way back into contention for top prizes this term, as even their recent wobble has left them only two points off top spot in the league and second in their European group.
