So here are Chelsea tough and tricky games left :
Tough: Liverpool, City
Tricky or moderately difficult: Sheffield Utd, Wolves
Here are our tough and tricky games:
Tough(not quite as tough as Chelsea's): Tottenham
Tricky or moderately difficult: Shieffield utd, Leicester
Now we are 3 points behind Chelsea but with favorable goal difference(though this is negligible because it's only 2 goals advantage, can always be overturned). Of course even the games where both of us are expected to win won't be easy nor guaranteed, especially since some of them are fighting for survival, not to mention both us and Chelsea have been inconsistent.
But if we focus on the main games to asses things, with us only 3 points behind Chelsea I'd say we're in a good position to nab 4th. I know Chelsea are ahead of us currently(by 3 points) but given the run of fixtures remaining and the small gap in points(a gap which can be overturned with 1 result), I'm feeling pretty good about our chances to make it.
