Lionel Messi bagged two goals and an assist despite only coming on in the second half against Hong Kong.
The second goal was pretty much trademark from Messi, who travelled with the ball on his left foot before firing home.
Ever Banega got the goals rolling on 19th minute. Goals just before half-time from Gonzalo Huguain and Nico Gaitan made it 3-0 at the break.
Gonzalo Higuain bagged number four before Lionel Messi took over when he was introduced on 60 minutes.
The Barcelona forward scored twice and set up another for Gaitain in the final 25 minutes. He could have gotten a third late in the match with a left-footed curl that was saved by Hong Kong keeper, Yapp.
