Arsenal midfielder Mesut Ozil says the transfer market has gone crazy.
The German joined Arsenal for a club-record £42.5million in 2013 although that fee has been blown out of the water by deals in the past two summers.
"No individual around the world is worth €50m," Ozil told Express.de.
"That's why in football we have to be careful not to lose our grip on reality.
"And it is also important that, through the opportunities football offers, we do good and help."
