That was more like it from the Gunners, Arsenal got their groove back by thumping the Croatians by 3 goals to 0.

In the last few weeks it looked as if Arsenal had lost a bit of sparkle and zip all over the pitch. We have struggled to reach the heights of our Manchester United display and I think a lack of options due to our injuries has played a big part in that.

What was instantly noticeable was the speed and crispness of our passing, it was far quicker than it has been for a few weeks.

Joel Campbell put in his best display in an Arsenal shirt since coming into the squad. He has always worked hard but his link play with his team mates seemed erratic. Last night he was purposeful, direct and clean in his passing.

The first goal on 28 minutes was a thing of beauty, starting with a twisting and turning Santi Cazorla deep in the right back spot, an exchange of passes between Campbell, Bellerin, Özil and Giroud saw the ball moved up the pitch to Alexis on the left side, Alexis played an Özil style pass to the head of Özil who produced a brave Alexis style finish.

The second goal only a few moments later saw Nacho Monreal burst into the box and pick out Alexis Sanchez to score his first goal in 6 games for Arsenal. Mesut Özil, Alexis Sanchez, Joel Campbell and Santi Cazorla behind them were simply too much for the visitors.

The intensity in our pressing had returned and we managed to pen Zagreb in their own half and dominate the game. It was interesting to see Mesut Özil play so close to Giroud and he often looked to get into scoring positions. He had two more chances to score during the first half, one shot wide after a twisting run and the other saved following a cut back.

Joel Campbell was definitely quieter in the second half and did not get on the ball quite as much as he did during the first half. But in 68 he produced the pass of the match, cutting inside on his left foot, he spotted Alexis making a diagonal run inside the box, and his reverse pass sliced opened the Zagreb defence and landed at the feet of Alexis who rounded Eduardo and thumped in his second of the night.

Alexis had moved into the centre forward position at this point, Wenger explained that Giroud had a slight ankle knock so it was Aaron Ramsey returning from injury who replaced the Frenchman.

I am still intrigued to know what Alexis Sanchez could do longer term at centre forward but Arsène believes he is more useful to the side from a wide position it seems,  and he would know given that he watches these players every few days on the training ground.

With the score safe, Arsène gave Calum Chambers a go in midfield in place of Santi Cazorla. Perhaps that move was preparation just in case an emergency arose.

Debuchy also came on for Bellerin which makes sense as the Spaniard has only recently returned from injury, the last thing we need is him hobbling off the field once more.

So Bayern Munich did what we expected Bayern to do and they brushed aside Olympiacos. So as we thought, our fate and the Greeks for that matter, goes down to the final game. We need to better their result against us in the first game at the Emirates, we do that and we finish the group in second place and through to the knock outs, we don't and we enter the strange and weird world of the Europa League or is it Europa Cup? I don't know and that is for another day.

We got the result we wanted last night and also got a glimpse of some of our best football so that is just what we need to boost us domestically. How Alexis is producing what he is doing in his last two games after so many matches without rest is quite incredible really. Mesut looked hungry and Campbell looked a different player from the Campbell who came on and missed a great chance only a few days ago. With Ramsey back playing once again and Oxlade-Chamberlain along with Walcott only around the corner, we can allow ourselves a smile once again.

It's a fickle game this football lark.
