I would choose the Premier League because four times in a row has never been done in history. And I'm sure that's what Pep has in mind this season as his number 1 objective.
He even mentioned it in his reaction post match.
“It is football, it happens. We do not have to win the Premier League. No team ever has won four Premier League in a row.
“We are behind but it is October. Last season it happened but the season is long.
“We have people coming back and we will try to beat upcoming opponents like Brighton and United. We will continue.”
