Lionel Messi scored his sixth Champions League hat-trick as rampant Barcelona inflicted on Celtic their heaviest ever European defeat.
The Argentine 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 Suarez scored with a volley and then a side-footed finish.
In their two full seasons together at the Nou Camp, Messi, Neymar and Luis Suarez have scored a combined 253 goals and have assisted 120 more.
