Arsenal get back to winning ways in the Champions League with a commanding victory over Sporting at Estadio Jose Alvalade.

It's a kinder format that leaves plenty to be decided on the final day. Smaller clubs will unquestionably advance to the direct elimination stages of the competition, where the stakes and pressure are higher. Upsets in the playoff round are likely to happen, with plenty of Davids getting a chance to dispatch any struggling Goliaths.

The Gunners look to maintain their unbeaten record as they host the Portuguese league leaders at the Emirates.
