AS Roma forward Paulo Dybala said it was a big blow to be left out of Argentina's Copa America squad and that he had been confident of selection for the tournament in the United States. The 30-year-old scored 16 goals in 39 appearances for Roma last season but struggled with injuries and was the surprise absentee from Lionel Scaloni's 29-man squad named last week. Scaloni still has to cut three players from the list for the tournament, which runs from June 20 to July 14.
