Arsenal boss Mikel Arteta admits momentum is with them after victory over Bournemouth.
The result keeps Arsenal five points clear at the top of the table.
Arteta said: "That's four in a row - winning four games in a row in the Premier League is very difficult. We've won three in a week, which is even harder, and we've done it in various ways. That should generate more belief.
"Today, a lot of things went against the team. Our fault for the first one, then the fact we weren't scoring, the situation with Leo, the set-play they had when they scored.
"The team still found a way to win the game and that's really positive. "
