AC Milan goalkeeper coach Nelson Dida says Mike Maignan still has much to learn.

Dida has been working with the Frenchman for almost 18 months.

He said, “I'd put Maignan among the top six to 10 goalkeepers in the world right now, but he is improving all the time.

“I taught him what I had learned. Coming to Milan means taking on a big responsibility.

"He was lacking the basics in terms of technique, so he is improving every day in that respect."
