Barcelona have enjoyed a stroke of luck in the Champions League. They were drawn against Manchester United, with the second leg away from home. However because of UEFA rules, that was changed so the return is going to be at Camp Nou.
Man City were also drawn at home in Manchester against Tottenham in the second leg and UEFA rules say that whichever team has the lower clarification in the Premier League, will have to switch the order of their games around.
So Man City will face Tottenham at their new stadium first then host the return nat the Etihad.
United will play Barca at Old Trafford on April 10 and then head to the Catalan capital on the 16th.
