4 Things We Learned From Manchester City's Emphatic Win Over Arsenal on Sunday

Manchester City got back to winning ways at the Etihad, as they beat Arsenal 3-1 on Sunday afternoon.

The Citizens prevailed thanks to Sergio Aguero's hat-trick, which included his opening strike after just 46 seconds. Laurent Koscielny scored the Gunners' only goal of the game, but it wasn't enough as City triumphed on a successful night at the Etihad.

Here's a look at four things we learned from Sunday's Premier League clash.

1. Manchester City Rise to the Challenge Under Pressure

After a devastating defeat at the hands of Newcastle United last Tuesday, Manchester City needed a big reaction. They began brilliantly, scoring within 46 seconds of kick off, and from then on were in complete control, doing their job in what was a crucial match for the Premier League title race.

Pep Guardiola has trained his team well to react to defeats - this season three of their four league defeats have been followed by a win. City knew that they needed to win if they were to keep up with league leaders Liverpool, as they cut the gap to just two points.

With the pressure constantly on Guardiola and his players, they stayed composed and focused to pull off another crucial win. Although the defeats can and will be crushing, Manchester City need to be able to react well as they did on Sunday if they want to retain their league title.

2. Arsenal's Defence Is Not at the Standard of a Top-Six Side

Although Arsenal did show good signs going forward, it was their defensive performance that proved their downfall against the reigning champions. Time after time their back four was cut open by City's attacking stars, which proved costly in what was a disappointing defeat for the Gunners.

Frankly, their defence was woeful against City and has been far from up to standard this season. Arsenal conceded 36 goals already this campaign, labelling them as the eighth-worse defence in the league, behind the likes of relegation battlers Crystal Palace and Newcastle.

It can't be ignored that they have injury concerns, with Shkodran Mustafi going off injured and Hector Bellerin and Rob Holding sidelined for the remainder of the season. However, they should have stronger defensive backup options, which the lack of will continue to be their achilles heel this season.

3. Sergio Aguero Will Turn Up When He Is Needed Most

In seven-and-a-half years at City, Sergio Aguero has always been the man to turn to. The club's all time leading goalscorer has always been there to provide the goals for the Citizens, and that was certainly the case on Sunday with his 18th, 19th and 20th strikes of the season.

What is even more impressive is his record against the big six. Since arriving in England in July 2011 Aguero has scored 39 goals in 63 meetings, more than anyone else, 18 goals clear of the next best player - Tottenham forward Harry Kane.

In a game where Manchester City needed big performances from everyone, their star striker certainly delivered with a wonderful hat-trick. It will be a relief for Guardiola and the City fans to know that they have a world class striker to turn to when they need a big result.

4. Arsenal's Away Form Really Needs to Improve

Arsenal have now gone six away league games without a win, with their last victory on the road coming against Bournemouth on 25 November. For one of the Premier League's big teams, it is not good enough for the Gunners to have such poor form away from home.

It also shows in the overall table on away form this season. Arsenal are ninth in a table which comprises of only away games, having won just a third of their matches away from the Emirates. This is compared to rivals Tottenham, who have won 11 of their away games.

The truth is that the Gunners have a lot of potential and are capable of outstanding performances, which we have seen this season. However, they cannot continue the season with such poor away form, an issue that Emery urgently needs to address.
