After beating beating Celta Vigo in the first leg of their Europa League semi-final thanks to a Marcus Rashford free-kick, Manchester United have a date with Ajax or Lyon in Stockholm if they can finish the job at Old Trafford in the second leg. Jose Mourinho can therefore earn entry into the Champions League through the back door if he succeeds on May 24. The Red Devils will go straight into the group stages after Atletico's defeat to Real Madrid. United would have been forced to go through qualifying if Diego Simeone's side had finished fourth in La Liga and been successful in Cardiff next month.With United one point outside the top four, they could well need to win the final to stand a chance of playing in next season's Champions League group stage.But if the Red Devils do triumph, what does that mean for the top four in the Premier League? A maximum of five teams from any one country can qualify for the Champions League, so the fourth placed side in the Premier League would only be in danger of missing out if both winners from the European competitions were English and neither finished inside the top four. Only then would fourth place be relegated to the Europa League.The top three in the Premier League go automatically into the group stages of the Champions League, while fourth place will be forced to go through a play-off, according to and analysis on the Mirror.After Leicester's elimination at the quarter-final stage to Atletico Madrid, fourth place will not be in danger of being relegated into the Europa League.Because Juventus and Real Madrid will all qualify for the Champions League through their league positions directly into the group stage, the Europa League winners will qualify for the group stage.
