The former Bayern Munich star feels that die Mannschaft lack a player who can really make a difference, and feels the team does not depend too much on Bastian Schweinsteiger
The former Bulgaria coach feels that attacking midfielder Mesut Ozil has plenty of quality, but does not believe the Real Madrid star is of the same level as Barcelona's Lionel Messi.
"I'm always pretty cautious when people say that one player could single-handedly help his side to a trophy. Ozil obviously has a lot of quality, but so does Sami Khedira as holding midfielder," Matthaus said to Eurosport.
"Germany don't really have one superstar like Lionel Messi, who could make the difference all by himself."
Matthaus then went on to discuss the importance of Bastian Schweinsteiger, who has recently returned from injury, but stressed that Joachim Low's side do not depend on the Bayern Munich man.
"He's still not fully recovered from that calf injury, and is fighting the disappointment of the lost Champions League final. Nobody is irreplaceable in the national team, though. We don't depend on Schweinsteiger."
Germany lock horns with Portugal on Saturday in Lviv, before facing Netherlands and Denmark.
