While in the FA Cup Burnley will face Southampton in the Premier league this team is not so impressive losing more than winning so the points are very far with other teams.
But I see Southampton cannot be underestimated because if they compete with Burnley then this will be an equal match.
It's an almost equal match, despite the difference in leagues. Southampton could very well be in the championship next season with Burnley in the premier league.
It's a match that can go to extra time an possible penalties.
