Italian champions AC Milan have completed the full signing of Ghana's Kevin-Prince Boateng from Genoa.The 24-year-old played for Milan last season but was part owned by Italian rivals Genoa, who bought him from English club Portsmouth a year ago.Genoa president Enrico Preziosi said a deal had been struck for Milan to buy out Boateng's contract."Two clubs like Genoa and Milan can't argue so we've made an agreement, he is entirely a Milan player," he said.The two clubs also reached a similar deal for Nigeria's Nnamdi Oduamadi to join Milan as well, he too had been co-owned by the two clubs.Preziosi didn't divulge any details of payment between the clubs.Last week both Milan and Genoa had accused the other of trying to move the goalposts on an agreement struck a year ago.Source; BBC
