Manchester United will definitely play in the Champions League next season because they are going to defeat Tottenham in the finals and win the league. Amorim is a coach with a good playing pattern and the players have begin to understand themselves better when they're with the ball. This gives me assurance that United can make it to UCL next season.
Not only that, but Amorim is also quite familiar with the playing pattern of the opponent he will face later in the final match because Tottenham is a team that also comes from the same League as him for now. So Amorim will use tactics that are quite precise at this time because during Manchester United's time in the Europa League, they have never been defeated by any opponent so that this achievement will be continued by Amorim with his players at Manchester United in the final match later.
