Arsenal are within reach of an unprecedented domestic and European double, with statistical model Opta giving the London club a 46.5% probability of winning both the Premier League and the UEFA Champions League this season. The Gunners lead the Premier League table by five points with three games remaining, and face reigning champions Paris Saint-Germain in the Champions League final — their first appearance in the competition's showpiece event in 20 years. Should Arsenal clinch both titles, they would become only the fourth English club to achieve the feat, joining Liverpool, Manchester United, and Manchester City.
