Over the last 10 games Chelsea have only lost 3 more points than us (we've got 24 from last 10 them 21).
Even if we were to beat them (which won't happen), then we would still need them to drop 9 points from 10 games and considering they only have the league to focus on now, that simply won't happen.
That would also assumer us winning all 9 of our remaining games, which again, isn't going to happen
