AC Milan vice-president Adriano Galliani admits they're trying to get to the bottom of Alexandre Pato's injury woes.
The Rossoneri are determined to find out the cause of Pato's constant injuries.
"We confirm a trip in mid-December for an important visit to Duke University in North Carolina," Galliani explained.
"Pato came to us in August 2007 and until December 31, 2009 did not experience any major injuries. In 2010 he has missed 152 days for various injuries. We need to understand why. We need Pato."
