The Argentine has featured in all but one of Man United’s Europa League games this season, claiming seven clean sheets along the way.
It was thought by many that, with United now in the final, David de Gea should replace the Argentine for the crucial clash with Peter Bosz’s side.
But Mourinho, speaking after the game, made it clear that Romero would keep his place in the side.
“We have two fantastic goalkeepers and I never saw two keepers such friends in a position where there is a rivalry,” he said.
“We are speaking of the Argentina and Spanish national keeper. It is fair Sergio is going to play the final and David accepts that. If everything goes normal Sergio plays in the final.”
“I have to give some minutes to everyone because we have only 15 players. We have no more so I have to play them, but play them mixed and in periods. I have no other solution.
“In the Premier League we can only finish 5th or 6th. We can not finish 7th or 4th. We can win a trophy and play Champions League next season so that is the game. Against Arsenal we did not throw the game away. We are not going to say the matches are not important but we have one that is more important than others.
“In the last game I am going to make a lot of changes so I hope Crystal Palace does not need to win the last game.”
Abandoning Romero just as United approach the zenith of their European campaign would be painfully cruel on the Argentine. Not only would this be demonstrative of a complete lack of integrity; it would be wholly unfair on somebody who has, whenever called upon, delivered reliable performances in Europe.
Not just a matter of principle, then, but indeed merit instead. Romero deserves to start ahead of De Gea in this competition and supporters will hope to see the 30-year-old claim his eighth clean sheet in Europe this season.
