After a familiar foreboding engulfed Arsenal a couple of weeks ago, two key victories have reignited the positive mood around the Emirates Stadium.
The Gunners were impressive in wins over Chelsea and Manchester United, keeping their top-four hopes alive. Tottenham Hotspur's draw against Brentford last week even gave Mikel Arteta's team a narrow advantage going into the sharp end of the season.
Sunday will be an intriguing test at West Ham United. Although the Hammers have had another fine season, the fact the game is sandwiched by both legs of their Europa League semi-final should give the Gunners an advantage.
