Rino Gattuso is backing AC Milan's move for Valencia midfielder Yunus Musah.
Gattuso has coached both clubs and worked with Musah last season.
He told TMW: He reminds me of the Frank Kessie of before. First of all, he is a good boy, then he has great strength in his legs. My advice is this: you have to wait for him.
"I consider him a great buy."
Milan aim to sign Musah for around 20m.
