5 Things We Learned From Arsenal's 2-1 Premier League Victory Over Bournemouth

Arsenal closed the gap on the top four on Sunday afternoon, as their gritty second half performance saw them triumph 2-1 in a fiercely fought contest against Bournemouth.

Jefferson Lerma's outrageous, volleyed own goal gave the Gunners a lead midway through the first half, before the Cherries grabbed an equaliser on the brink of half-time - as Joshua King clipped a sumptuous finish into the top corner

Arsenal rallied, and Pierre-Emerick Aubameyang tapped home from close range in the second half. With a precarious lead hanging in the balance, the Gunners withstood some rapid attacking play from the hosts - with Junior Stanislas' free-kick dipping agonisingly over the crossbar in the final action of the match.

As always the game provided us with a number of interesting talking points, so here's five things we learned from Sunday's clash.

5. Arsenal Look More Than Capable of Securing a Top 4 Finish

Grit and determination - two words that haven't been associated with Arsenal in a long time.

But Unai Emery's side are rapidly becoming just that, and have developed an impressive ability to grind out results in matches where they'd have crumbled in seasons gone by.

If they keep up their fine form, there's no reason why they can't earn a top four finish this season.

The future looks bright for Arsenal; with a decent amount of investment next summer, and more experience of their manager's style of play, the Gunners are more than capable of becoming a regular top four side again.

4. England Made a Big Mistake Not Snapping Up David Brooks

It's hard to understand how England let Bournemouth's David Brooks slip through the net and commit his allegiance to Wales.

The Warrington-born wonder showcased his technical skills and dynamic movement again on Sunday, as he put in a highly accomplished performance for a player with such limited Premier League experience.

The 21-year-old looks to have a fine career ahead of him, and the England selectors will be frustrated to have let a former Under-20s Three Lions international slip through the net.

3. Sokratis Could Be the Centre-Back Arsenal Have Been Crying Out For

Arsenal have been desperate for a top quality centre-back for a while back now, but Greek powerhouse Sokratis is looking like he could finally be the answer.

The former Borussia Dortmund man was excellent against the Cherries, and kept prolific goalscorer Callum Wilson snugly tucked away in his back pocket for the whole match.

With the Gunners now trailing a back three, Sokratis is less exposed, and he seems to be flourishing thanks to the change of tactics.

2. Bournemouth Need to Find a Way to Sustain Their Momentum

Bournemouth are a bit like that friend you have who starts the night sinking pints at breakneck speed, before having to be tucked up at 9pm have drastically overestimated their ability for endurance.

The Cherries are fast starters, there's no denying it, but their inability to keep a steady pace is starting to become a problem.

When Arsenal scored their second goal, Eddie Howe's side looked to have run out of steam, and didn't have the energy required in the tank to launch another comeback.

1. Alex Iwobi Needs to Work on His End Product

Theo Walcott's big problem for Arsenal was that, time and time again, he failed to provide a clinical pass or deadly finish when called upon.

Iwobi - Walcott's successor on the wing - still has a lot of time ahead of him, but his tendency to burst past opponents before faltering at the last moment is starting to hamper his play.

The Nigeria international put in a poor performance against the Cherries, and will struggle to stake a claim for a regular starting spot if he can't improve his end product.
