Southampton boss Mauricio Pochettino rates Arsenal as title favourites.
Saints play Arsenal this weekend.
"I would say that the team that we're going to play against on Saturday is the one that's playing the best football in the league," he said.
"I think they can win the league, but I also think that there's other teams that are going to be in the running to win the league.
"I think it's going to be a hard-fought competition throughout until the end of the season. It's going to be very competitive and I think it's going to be a very exciting end to the season."
