Can the Gunners break the curse?

Arsenal Football Club just beat Real Madrid in the UEFA Champions League quarter-finals. They won 2-1 in the second leg at the Bernabéu Stadium last week after winning 3-0 at home in London the prior week. This win secured Arsenal's place in the semi-finals for the first time since 2009. This victory over the Spaniards was very unexpected. Real Madrid is by far the best team in Champions League history. They are, many would argue, the best team in the world and have the best player in the world in Kylian Mbappé. Despite these odds against them, Arsenal just beat Real Madrid not once, but twice in a row. After completing this 5-1 aggregate victory they now face French team Paris Saint-Germain F.C (PSG) in a two legged Semi Final, at home on April 28th and away in Paris on May 7th. 

Manchester City win league and FA cup and are on the verge of historic treble in Europe

There is a town in the north of England where soccer (“football” in the UK) is religion. The town is Manchester.  There are two main rival teams there that compete in the English Premier League, the highest professional soccer league in Britain with only the best club teams playing in it. If ticket prices and club valuations and player salaries are anything to go by then, all things equal, the English Premier League is probably the strongest and most competitive sports league in the world, of any sport.
