Toni Kroos has conceded that Real Madrid's pre-season tour is "exhausting", after the club finished the Australian leg of the schedule with a 4-1 victory over Manchester City on Friday.

The Spanish club also played Roma on the tour but were eventually beaten on penalties, leaving the German midfielder tired from the trip.

"It's normal for this club, but it's a long trip that's also become exhausting," Kroos told reporters.

"We trained a lot and were often in the hotel or the trainings grounds or in the stadium so we didn't see too much of Australia.

"Maybe I will come here another time on my own. I prefer it if it's warm. If I come next time, it will be in summer."

Real now head to China to take part in the International Champions Cup and then travel to Munich to play in the Audi Cup, before finishing their pre-season tour in Oslo.
