Attention will always be focused on the big clubs, especially since Liverpool currently has a star-studded squad. We'll see what Arsenal does this season; they've started the season quite well, and hopefully their performance will remain consistent even when faced with a busy schedule.
The match between Liverpool and Arsenal on Sunday won't be the title decider but it will give us a closer look on which of them has really done a good job during the off season. Arsenal to me has been more convincing and they have faced a bigger team based on history in Manchester United than Liverpool who needed late goals to finish off Newcastle and Bournemouth.
