Ronaldo may feature for Milan against Empoli in the weekend after recovering from a nagging muscle injury, media reports in Italy said. The Brazilian star picked up the injury over the summer and it was wrongly diagnosed, costing him extra time on the sidelines. He will undergo final tests on Tuesday before being declared as fit for Serie A action. Ronaldo's comeback is good news for coach Carlo Ancelotti, who has been seeing shaky performances from strikers Alberto Gilardino and Filippo Inzaghi recently. The European champions have won only twice in their first seven league games.
