Keisuke Honda's presence at AC Milan is having an effect in revenue.
Gazzetta dello Sport says Milan have agreed a €3 million deal with Japanese company Toyo Tires. They are the second Japanese sponsor to come on board since Honda's January arrival from CSKA Moscow.
Milan chief Barbara Berlusconi remarked: "We are delighted to welcome Toyo Tires.
"We begin a partnership that reflects the increasingly global reach of our club and we are delighted to partner with a brand as important as this at the international level."
