Arsenal will travel to Udine, Italy to face Udinese in the second-leg of the Champions League Qualifier at the Stadio Friuli on Wednesday.

These are very early days in the season, but Arsenal already find themselves facing probably the most defining match of their whole campaign. Much of Arsenal's year clings on the outcome of this match. They've have a 1-0 advantage going into the second leg and they'll hope to add to that and seal a berth in the group stages of the Champions League.

The consequences if Arsenal fail to do so could be dire at best. First of all, a place in the group stages is, reportedly, worth around £30 million.If they don't qualify, they will find it harder to spend the proceeds from the sale of Cesc Fabregas and Samir Nasri. Secondly, without a place in the Champions League, Arsenal will find it hard to convince the likes of Eden Hazard and Yann M'Vila among others, to move to the Emirates, especially with time running short before the close of the transfer window.
