Black players of Milan's under-10 team were allegedly subject to heckling and racist abuse during Sunday's 4-0 win over Paris Saint-Germain in the Universal Cup. Milan says it does 'not want to magnify the issue' and 'truly hopes that these reports aren't true or that it was simply a sporadic incident.'
