Real Madrid are stronger and more mature than last season, when they failed for a third year to win the league title, according to their German playmaker Mesut Ozil.
After a USA tour in which they went undefeated against Los Angeles Galaxy, Chivas and Philadelphia Union, the squad resumed training in Madrid before they face Hertha Berlin in a friendly in the German capital on Wednesday.
"Real Madrid are stronger and more mature than last year," Ozil told a news conference. "We have the potential to beat any rival and our aim this season is to win many titles."
Real finished last season second behind league winners and arch-rivals Barcelona for the third successive year, coach Jose Mourinho's first season in charge.
The club's only silverware was a first Copa del Rey triumph in 18 years. Ozil declined to discuss the next Spanish Super Cup, which will be played over two legs on 14 and 17 August against Barcelona.
"I don't want to discuss this subject. We are focused on our preparation phase and our only concern just now is that all the injured players have recovered by 14 August," the 22-year-old FIFA World Cup™ star said. Sami Khedira, Nuri Sahin and Sergio Ramos all finished the USA tour on the injured list.
