We can't judge West Ham United as small team but in realistic they can't consistent on top performance actually last end primer league games where they have chance for finish on 4th standing position place but at least they can't play with top performance. After defeating by Tottenham Hotspur exactly still have chance for West Ham United as finish on 4th position but several match left have waiting by Arsenal, Chelsea and Manchester City. Still have another option for getting champion league spot maybe become the champion on UEFA Europe League where West Ham United success on quarter final right now.
West Ham have been having an extraordinary season. But at this stage of the championship, I think it will be very difficult for them to reach 4th place. Mathematically it's still possible, but it would be necessary for the teams in front to start losing several games.
In the best case scenario, they may even manage to stay in 6th place, if Man United continues to play very irregular games.
Westham United still have a chance to make the top four this season. The title challenge is still very open and they’re just 6points below Arsenal. They are still competing in the Europa League which is their primary focus right now not having the squad depth to withstand this pressure that comes with competing for both titles is what might or will sink them in the EPL. They have made it through to the quarter-finals, while they are currently in seventh place in the Premier League. Even though Arsenal are the favorite to finish in the top four ahead of Tottenham Hotspur, Manchester United, and West Ham, I still believe that anything can happen before the end of the season.
It will be very hard for westham to finish in the fourth position because the team ahead of them(Tottenham, arsenal and Manchester United) have a better squad than them and more depth than them and that's an disadvantage to them in there fight for the top four,and in there adventure to qualify to the champions League through Europa League,that one will also be difficult because Barcelona is still there and the Spanish giant are in strong form,it might be a mighty to high for them to climb.
What you say makes a lot of sense, even though West Ham still have a chance to play in the Champions League next season. But to reach 4th place
in the Premier League is very difficult for West Ham, besides competitors West Ham playing much better than West Ham. The remaining 8 matches
in the Premier League West Ham still have to face several strong teams which makes West Ham drop points. Whereas if West Ham wants to move up
to 4th position West Ham must win all the remaining matches in the Premier League. Then if West Ham want to go through the Europa League route,
I doubt West Ham can win the Europa League this season, because in the Europa League there are Atalanta and Barcelona who are much stronger
than West Ham. Especially Barcelona whose performance has been getting better in the last few games, so West Ham do need a miracle if they want
to win the Europa League trophy.
