The former Bayern Munich midfielder went onto state that he expects more from the 27-year-old.
“He [Ozil] is too inconsistent [to be named world class], I expect even more from him,” Matthaus was quoted as saying by ESPN.
“Now and then, he hides and you can’t see him just like in the 4-0 defeat at Southampton.”
Matthaus’ comments come amid Ozil’s impressive run of form lately. The 27-year-old has provided 16 assists in 17 Premier League games which is more than any other player in England and the top five leagues in Europe including France, Italy, Spain and Germany.
Ozil has won the Arsenal player of the month award for the last two months for the north London club and is expected to win the away for a third consecutive time for December.
Arsenal take on Sunderland in the FA Cup this weekend and will look to extend their lead at the top of the Premier League next week when they face Liverpool.
