2.18 ppg would be 41 points in the remaining 19 games. Which equates to roughly 13 wins 2 draws and 4 losses. However it won't work like that. I firmly believe there's going to be 3rd and 4th up for grabs right until the last game of the season.
Of course we need to vastly improve, but its doable, especially with Partey back.
Think the point is it's doable but extremely unlikely. We're halfway through and have the same goal difference as West Ham, and there are no January signings on the horizon to come in and make a difference. But I agree this season is weird so i'd optimistically say that 6th is doable if everything goes our way.
