Of course, the Premier League has this very distant gap. Is it impossible? No. But we know are in a much more difficult reality than the teams that are up there. We play in the most difficult league in the world, where 10 points can suddenly become one, two, or zero in a month.""All the clubs are a little messed up and the results can fluctuate in several ways and we can also fight for the Premier League. The Europa League is the title that we have to aim for this year, it is the title that is achievable for us," added Luiz.
