Fenerbahce coach Zico is confident Ronaldo will rediscover his best form at AC Milan.
Zico said of his fellow Brazilian: "Ronaldo is always Ronaldo. It seems to me he is rebuilding his career at Milan after his problems in Madrid."
On the Serie A championship, Zico added: "Last season Inter Milan won without a challenger, but this year it will be very different. The championship will be very competitive with four teams all capable of winning.
"Inter as always, then Milan, then Roma and also Juventus."
