Hector Moreno is delighted to be joining Roma.
The 29-year-old completed his €5.7m transfer from PSV Eindhoven last week.
He was given extra time off after Mexico participated in the Confederations Cup last month.
“I am very happy and enthusiastic about this new adventure," Moreno told reporters.
“I haven't yet spoken to (Coach Eusebio) Di Francesco, but I will soon."
