Gotze rejoined Dortmund from Bayern last summer but has endured a frustrating season so far and has missed the past couple of Bundesliga games through injury.
As reported by Sport.de, Matthaus said: “Honestly, even if it sounds a bit nasty, if it does not work for Gotze at Dortmund, he has to go to China. Gotze certainly does not want to make less money.
“He will not go to Schalke, he will not go to Leverkusen, Gladbach cannot afford to sign Gotze. Top clubs from abroad aren’t that interested anymore.
“If he does not get in the team at Dortmund, and has the same salary demands, then he will be off to China – but that would be a poor test for a 24-year-old.
“He has to change, that’s obvious, he’s missing the speed that is the thing in today’s football, and players like Xabi Alonso can balance it, but not an offensive player like Gotze.”
Gotze’s struggles are summed up by the fact that he has scored just once in the Bundesliga this season.
The German remains a fine distributor of the ball – he has an average pass accuracy of 83% in the Bundesliga this season – but surely must be frustrated with his current situation.
At the age of 24, Gotze still has much time on his side to get his career back on track and will be hoping to make a major impact for Dortmund once he returns to full fitness.
Next up for Dortmund is an away game against Freiburg on Saturday.
