Messi leads Barcelona in demolishing Manchester City
Bravo, the goalkeeper controversially signed by Guardiola from Barca this season, was sent off for handling outside the area after blundering an attempt to play out from the back.
Messi, who had already scored one in a breathless Champions League Group C clash at the Nou Camp, took further advantage with two more and Neymar, after missing a penalty, added a late fourth.
Barca also finished the game with 10 men after Jeremy Mathieu – a 39th-minute substitute for the injured Gerard Pique – was dismissed for two bookings in quick succession.
It proved far from a happy homecoming for the revered Guardiola, who made a huge call before kick-off by leaving star striker Sergio Aguero on the bench.
His reasoning was that he wanted more midfielders, presumably to combat Barcelona’s attacking arsenal, but the tactic failed.
Ozil, Sanchez on rampage, as Arsenal thrash Ludogorets 6-0
Mesut Ozil and Alexis Sanchez showed why their value to Arsenal is priceless as the peerless duo inspired a 6-0 thrashing of Bulgarian minnows Ludogorets in the Champions League on Wednesday.
Gunners boss Arsene Wenger has urged Ozil and Sanchez not to get greedy after reports they both plan to demand Arsenal increase their wages to £250,000-per-week ($307,000, 279,000 euros) when contract talks are reopened later this month.
Sanchez and Ozil’s current deals expire in 2018, but Arsenal want their prize assets to commit their long-term futures to the club and on the evidence of their swaggering displays at the Emirates Stadium, they should pay them whatever they want.
Sanchez was the catalyst for Arsenal’s romp as the former Barcelona star netted his sixth goal of the season with a quite brilliant first half chip, while German midfielder Ozil smashed a second half hat-trick.
Theo Walcott and Alex Oxlade-Chamberlain were also on the scoresheet for rampant Arsenal, who are top of Champions League Group A after three matches and well on course for the last 16.
Unbeaten in Europe this season, Arsenal have now won seven successive matches in all competitions.
