In conclusion, I can't fully believe that Brighton will be the team that surprises us all. Except for waiting for the next few matches when Brighton will face Liverpool and Man City who are currently the strongest teams in the EPL. If in that match Brighton can get a draw or not lose points, I believe that Brighton has a stable consistency and will be successful at the end of the season.
I don't think you get the question, it is not like the dark horse is going to go unbeaten and beat all the big teams, just a team that would surprise everyone and finish in the top four, like Aston Villa did last season and Newcastle in the season before that. Brighton have started very well, that is why people are tipping them to be that team, they have been strong in their last three games despite what you say, you cannot fault their victories based on the performances and conducts of their opponents.
Leicester did it once, and ever since then a lot of people keep waiting for another team to do something that crazy. But people forget that when Leicester did that, City wasn't this dominant, and Arsenal wasn't this great ,and Liverpool didn't had a huge Klopp period ever since then.
So when you think about it, premier league is much tougher right now compared to when Leicester did it, doesn't mean that Leicester did something easy, it was still near impossible, people became millionaires when they bet on them, so it's clear that we are not going to end up seeing something similar again. Brighton is great, but a top four finish would be the only thing they can pray for, nothing else would be realistic result for them and shouldn't be expected.
