Lionel Messi: "I missed nights like this".

Argentina striker Lionel Messi reacted to his double and goal in the MLS match against Philadelphia Union (3-1).

It was the Argentine's first game back from injury - he hadn't played since July 15, when he took part in the America's Cup final.

"I missed nights like this. Let's keep moving towards our goals," admitted 37-year-old Lionel Messi.
