#2 Southampton will fight for their lives
Southampton are definitely going to give Arsenal a very good fight on Sunday. They are winless in their last 5 games, and have lost 2 of their last 3 games this season.
They need to start picking up points before the winter schedule of fixtures kicks in. It will be extremely difficult for teams who are in the relegation zone by December to avoid relegation come the end of the season.
Thirdly, they have a new manager in Ralph Hasenhuttl. These players will be willing to prove to their new manager that they all deserve a place in the starting eleven. A game against The Gunners could be the perfect game to prove that to the man in charge.
It could also be a spring board to go on and deliver good results which might eventually see them escape relegation.
