yeah Chelsea is very unpredictable and very unstable team in the premier league this season . I think all of the top team are not sure to win against Chelsea but only Four team this season is making has place in the top four is Liverpool , Arsenal , Manchester united , and Chelsea . that's my predication for the premier league top four this season . and one thing Chelsea will give tough time to most of the top team this season note my predication .
You said Chelsea is unstable this season, but I always have confidence that Chelsea will win their match whenever they are playing compared to the other teams that you mentioned. Chelsea has won their last 5 matches that they played in the Premier League. I will say Chelsea is more consistent than the other teams that you mentioned because none of them have been able to win their last 5 matches, so in terms of consistency, I will say Chelsea is more consistent.
Your prediction for the top four is wrong to me. How will you even include Manchester United in your top four? And Manchester City is not included. How will Manchester United end the season above Manchester City? I don’t think that’s going to be possible, because United's performance is not so good also, and we all can see the position that Manchester United is currently in. It’s just going to be difficult for Manchester United to end the season in the top four this season.
