It was a good day for Arsene Wenger who saw his Arsenal side progress to the FA Cup final after a 2-1 extra-time win over Man City at Wembley.
Sergio Aguero had given City the lead after he raced clear of Nacho Monreal to give Pep Guardiola's side the lead.
The defender made amends just minutes later after he converted Alex-Oxlade Chamberlain's cross in the 71st minute.
The teams finished deadlocked after 90 minutes and it took an extra-time Alexis Sanchez goal to send the north London side through to a clash with local rivals Chelsea.
In the Premier League, Liverpool suffered a huge setback in the race for a top four place with a 2-1 home defeat against Crystal Palace.
Coutinho had set Jurgen Klopp's men on their way with a brilliant free kick only for former Anfield outcast Christian Benteke to return to haunt his old club.
Two goals either side of half time gave the Londoners a valuable three points and all but secured Premier League football for another season.
