Five things learned from Arsenal's West Ham win: Coquelin, Cazorla, Welbeck feature

Coquelin

Five conclusions from Arsenal's 2-1 win over West Ham United on Sunday afternoon.

Koscielny's return is huge

After months out of the Arsenal team, we finally saw the return of Lauren Koscielny to the Arsenal starting XI - and he made a noticeable difference.

Koscielny was superb in the air against the dangerous Andy Carroll, and was key in helping Arsenal keep West Ham at bay late in the game. His return is a huge boost to Arsenal's top four quest based on today's excellent display.

Wenger's Coquelin gamble paid off

With the likes of Jack Wilshere, Mikel Arteta and Aaron Ramsey out of action, Arsene Wenger brought Francis Coquelin into the starting line-up.

The Frenchman was recently on loan at Championship side Charlton, but impressed for the Gunners against West Ham, offering energy and bite in midfield. He may never be a regular, but he has made strides and could be seen as valuable cover in the coming months.

Wenger could still use Alex Song

Now, this isn't even to say that Song had a good game against his former club. Song was in fact disappointing, seemingly trying too hard to impress Wenger having been snubbed by Arsenal in the summer.

Rather, this is to emphasise how poor Mathieu Flamini again. The Frenchman did very little to help protect his back four, whilst Song at least tried to get attacks going from defensive midfield and was robust in the tackle. With other great displays this season, it's still evident that Arsenal could use Song.

Cazorla's fine form continues

The story in the early stages of the season was that Santi Cazorla was out of form and had started to enter a decline having not scored in the league since January.

Yet now, Cazorla has hit a superb run of form, and was instrumental against West Ham, driving forward and creating chances from midfield. Oh, and he scored a penalty. Which was from his own run into the box. Another top display from the Spaniard, who is improving again.

Danny Welbeck - a better player without Giroud?

Danny Welbeck's goal drought ended with a close ranger tap in, with the former Manchester United man flitting between a wide role and centre forward, regularly swapping with Alexis Sanchez.

The ability to do this is using Welbeck at his best, and it poses the question; is he better when Olivier Giroud is out of the team? The French international was ruled out having been sent off against QPR on Friday, and it may now be a case of Welbeck OR Giroud rather than both.
