The Champions League draw has changed this year. All the champions from a respective country go down one avenue called the 'Champions Route', whilst all the other teams are in entered in the 'Non-Champions Route'. Then each route is seeded and non-seeded, and that has seen Celtic - who were non-seeded - drawn against seeded Arsenal. The first-leg will take place in Glasgow, before the return at Emirates. It is the first time ever Arsenal and Celtic will have met in a competitive fixture. The non-champions route is littered with big clubs looking to make the group stages. Champions League stalwarts Lyon must overcome Anderlecht, whilst Sporting Lisbon will tackle Fiorentina over two legs. Atletico Madrid will be looking for a second straight year in the group stages and they will clash with Panathinaikos for the right.
