Arsenal has been strong in both attack and defence this season. And consistently they are playing well. In 7 matches they scored 17 goals and conceded only 7 goals. But their opponents were not very strong. Despite being able to play well against relatively weak opponents, I look forward to seeing how they fare against strong teams.
Statistics means nothing on the next game though. 3 out of 7 goals conceded were scored by Manchester United and comparing the statistics alone wont give you anything especially when Tottenham has pretty much the same statistic but with 1 more goal scored but if you take alook at the head to head statistics then you would notice that both of these teams did fairly well in their own home game
