Mourinho eyes first trophy as united take on southampton in efl cup final
I think there may be a slight issue here!
Jose Mourinho is no longer the manager of Manchester United. He was sacked by the club in December 2018 and has since been replaced by Ole Gunnar Solskjaer.
Additionally, the EFL Cup (also known as the Carabao Cup) is a domestic cup competition in England, and the final is typically played between January and February. If the article you're referring to is from a previous season, it's possible that Manchester United did indeed play Southampton in the EFL Cup final.
However, if the article is from a more recent season, it's unlikely that Mourinho would be involved in the match, as he is no longer the manager of Manchester United.
