For Ronny to take us into Europe we need Utd to win the League cup and FA Cup and finish 5th or City to finish 5th win a cup and Utd finish 6th and win a cup, basically we need the team that finishes in 5th and 6th to both win a cup.
A team winning a cup who finish in the top 4 would only effect us if the team finishing in 6th won a cup.
Also if both cups are won by top 4 teams, 7th is also good enough.
Easy, right?
We could of course end all this by finishing 5th or finishing 6th and hoping that a team in the top 5 won a cup.
