Luke Saxton writes: 'I am definitely seeing this game as a thriller, plenty to prove for both teams who both contain some exceptionally skilled and quick players. Inevitable comparisons between Cazorla & Hazard to be drawn. Arsenal may edge it 3-2 will Walcott being the hero! However I feel a 2-2 drawled likely.'
Manny writes: 'Not a gunner or Chelsea fan but gutted im at work and missing this game, Chelsea will have a real test against a team who are playing some lovely football, it felt at one point arsenal were the home team against city, if Gervinho had his shooting boots on who knows what score it would have been. Chelsea on other hand this is their real first test of the prem league season, after some fairly 'easy' fixtures if that's the correct term to use, they were shown the real test in Europe firstly against Athletico Madrid then a top side in Juventus, Arsenal you can say are just as good or even better. Im predicting either a draw or a Arsenal win. Lets hope it's a draw and man united take advantage against spurs to end on top of the table.'
