3. A tough opponent
Nottingham Forest have enjoyed a brilliant and perhaps surprising start to the season under the leadership of manager Nuno Espirito Santo.
Currently sat in fifth place, one place below the Gunners, Forest have picked up some impressive results so far this campaign. They are the only side to have beaten high-flying Liverpool, having picked up a 1-0 win at Anfield in September, and also drew 1-1 with Chelsea at Stamford Bridge. Chris Wood has been a standout performer for them in recent weeks.
Forest will no doubt provide Arsenal with a tough test on Saturday afternoon, especially with the prospect of going above them in the table. The Gunners must be weary of their visitors' brilliance on Saturday afternoon.
