The Argentina forward cracked in an early first goal in the Group C match.
Celtic’s Moussa Dembele had a penalty saved before Messi poked in his second.
In the second half, Neymar’s free-kick sailed into the net, Andres Iniesta volleyed a fourth, Messi slid home the fifth and Luis Suarez scored with a volley and then a side-footed finish.
