#3 Can Diego Costa continue his good run of form?
The Brazilian is turning out to be a nightmare for the opposition defence with his clever runs in behind the backline in recent times. Costa has been in stupendous form, scoring five goals in as many Premier League games.
Usually, Costa plays with more aggression but when it comes to Arsenal he mixes aggression with all kinds of mischievous activities. Without any doubt, Costa will look to wind up the opposition defence in every possible way and the former QPR manager Harry Redknapp believes that the home team will be finding it difficult to stop the 27-year-old striker.
"When he is focused, he has got that great ability of bending his runs brilliantly and timing his changes of direction to create space. These days, he is looking like the kind of world beater he can be and Arsenal have it all on to keep him quiet if he turns up at Emirates Stadium on Saturday in that kind of mood” Redknapp wrote in the Standard Column.
