The Manchester derby had talking points from goals, the individual brilliance of Kevin De Bruyne and, sadly for Claudio Bravo, poor goalkeeping.
Twitter users were quick to condemn the goalkeeper's first performance for Manchester City, which had a host of shaky moments.
Claudio Bravo. Worst Premier League goalkeeping debut of all time?

Claudio Bravo is terrible. ?

Great debut for Claudio Bravo today. Tried really hard but unfortunately couldn't win it for Manchester United.

SUMMARY: Cladio Bravo's performance in The Manchester Derby.

His spill allowed Manchester United's Zlatan Ibrahimovic to pull a goal back in the first half.
Man Utd back in it - Claudio Bravo fails to claim a free-kick and Zlatan Ibrahimovic scores with a fine finish.

Ibrahimovic. Had to be a Bravo howler, eh?
-- Sergi Domínguez (@FutbolSergi) September 10, 2016
Only a few days before, Ibrahimovic had sent Bravo some training gear with a message on Instagram reading: "Welcome to Manchester! Here's some training gear, you're gonna need it. See you Saturday."
Clearly the mind games worked.

Bravo also nearly gave away a penalty with a foul on Wayne Rooney, and some think it should have been given - particularly United manager Jose Mourinho.
Clattenburg reffed game well, though Claudio Bravo challenge on Rooney should have been a foul, yellow and pen.

Mourinho: "I am very disappointed in the two decisions of Mark Clattenberg Bravo should be red card and a penalty. Otamendi is a penalty."
-- Manchester United (@ManUtdUpdates_) September 10, 2016
Mourinho on Clattenburg: "Mark made two big mistakes. Bravo [on Rooney] is a penalty + a red card & another for handball by Otamendi." #MUFC

Can't wait for Mourinho to talk about that Bravo tackle on Rooney for the rest of the week now

The performance left some wondering if they could return the £14.5 million former Barcelona man.

Some couldn't help thinking of Joe Hart, who was replaced by Bravo.

And some questioned Pep Guardiola's decision to opt for a goalkeeper who is good with his feet ...
Imagine selling a goalkeeper because he can't play with his feet yet sign a goalkeeper who can't use his hands. Bravo ?
-- ?Jay? (@FreddoAkh) September 10, 2016
Well Pep likes keepers that play using their feet so understandable why Bravo can't use his hands.
-- Marwan A. (@MarwanAhmed_KF) September 10, 2016
>Bravo great with his feet ..... Pity about his hands ?
-- Rodney Marsh (@RodneyMarsh10) September 10, 2016
Bravo isn't at City to use his hands, give him a break.
-- D'Padre(TM) (@D_WarEagle) September 10, 2016
Despite all this, manager Guardiola said Bravo's performance was one of the best he had seen.

One thing is certain, Bravo will need to look a lot sharper if he's going to fit in for Manchester City this season.
Claudio Bravo. Welcome to Manchester.
