4 Things We Learned as Arsenal Beat Huddersfield 1-0 in the Premier League

Arsenal extended their unbeaten run to 21 games as they beat Huddersfield Town 1-0 in the Premier League on Saturday afternoon.

Lucas Torreira's goal was the difference, as he scored with an excellent overhead kick in the 83rd minute to secure victory for the Gunners.

Here are four things we learned from the match.  

1. Arsenal Will Really Take Some Stopping

In case 20 games unbeaten didn't prove it, Saturday's win definitely showed how hard it is to hold Unai Emery's Arsenal. Although Huddersfield were close to doing just that, they eventually prevailed right at the death.

Huddersfield fought all game to hold onto a point, defending for their lives and frustrating Arsenal - yet it wasn't enough as the Gunners appear to have a newfound belief that they will find a way to grind out wins.

2. Huddersfield Can Produce Strong Performances

Although they didn't get the result, Huddersfield produced a good performance at the Emirates. For a team who had one win in four and were facing a side who were unbeaten in 20 games, the Terriers didn't look half bad, and were unlucky to come away from London pointless.

As manager David Wagner said in his post-match interview: “It was another step in the right direction in terms of performance. We can take this, go forward and I'm more than excited about the next games that we  have in front of us.”

3. Granit Xhaka Is Improving Game by Game

Criticised heavily in the past for his defensive work, Granit Xhaka really put in a shift on Saturday afternoon. In an all round solid performance, he led by example as captain and was at the heart of every move in Arsenal's win.

The Swiss midfielder has been criticised a lot before, but on Saturday he was key to the Gunners' victory, and deservedly earned the plaudits for a strong performance against Huddersfield.

4. Aaron Mooy Is Key for Huddersfield

Huddersfield could've had one or two goals at the Emirates, but it seems that Aaron Mooy's lacklustre performance stinted their performance in the final third.

The Australian midfielder is one of the Terriers' key players, and his poor display was keenly felt as the Terriers lacked teeth in their attack.
