It seems like Brighton has a greater chance of qualifying for the round of 16 after the victory they achieved in the match against Ajax. This was quite an important victory for them because the additional 3 points made them sit in 2nd place. Apart from that, Brighton has a better opportunity in the next two matches because if they manage to achieve 2 win in the next match, it is very likely that they will qualify as group winner.
Brighton will most likely qualify from the group phase, I think winning one more match will make them qualify, of course they will chase victory in the remaining two matches and become group champions to avoid strong teams. The victory over Ajax opened up all these opportunities, but I am quite concerned about Ajax now, they are really down even though they used to be a strong team.
And for Brighton, this is a big opportunity for them to focus well on their the European league because the European league is one of the opportunities for them to win trophies this season. In the domestic league, of course Brighton has no chance of winning the title because other team are stronger than them, so the European league is a place where they have to fight as best as possible this season.
I don't think they can win the European League because the competition is certainly very tough, especially Liverpool and Leverkusen. Of course they will try their best but my prediction is that they will only reach the semifinals and this is an extraordinary achievement considering Brighton's development so far.
