Here are the different scenarios for Sunday when it comes to the top 4, Europa League, and relegation as well as the different tiebreaker rules (per NBCSports.com):
Top 4
Chelsea
-would clinch top-4 with win/draw v. Wolves OR Loss v. Wolves AND Manchester United win at Leicester City
Manchester United
-would clinch top-4 with win/draw at Leicester City OR Chelsea loss v. Wolves (The latter part of this scenario assumes Manchester United maintains their goal differential advantage over Chelsea, which is currently Manchester United +28, Chelsea +13)
Leicester City
-would clinch top-4 with win v. Manchester United OR Draw v. Manchester United AND Chelsea loss v. Wolves
Europa League
Wolves
-would clinch top-6 finish if they better or equal Spurs' result
Spurs
-would clinch top-6 finish if they better Wolves’ results
And as has been mentioned on here previously, 7th would qualify for Europa League if Chelsea win the FA Cup.
Relegation
Aston Villa
-How could Villa go down with a win? If Watford beats Arsenal by at least two more goals than Villa defeats West Ham, it will climb over the Villans.
-Similarly, if Bournemouth draws or loses, and both Villa and Watford lose, Villa could go down if it loses to West Ham by at least two more goals than Watford loses to Arsenal.
-If both Villa and Watford draw, Villa stays up.
-If Villa draws and Watford loses, Villa stays up regardless of what Bournemouth does at Everton.
Watford
-A win over the Gunners would be enough if Villa loses.
-A draw would be enough if West Ham beats Aston Villa.
-Watford could even stay up with a loss if Bournemouth draws or loses and Villa loses to West Ham by two more goals than the Hornets loses to Arsenal.
Bournemouth
-The Cherries need to win at Everton. Anything less and they’re down.
-If Eddie Howe’s men take down the Toffees, they also need Watford and Villa to lose.
Tiebreaker scenarios
This is the order and format in which league position will be sorted by if teams finish level on points:
-Goal difference
-Goals scored
-Points won in head-to-head meetings
-Away goals in head-to-head meetings
If the teams still can’t be separated after the above tiebreakers, a playoff will be arranged (at a neutral ground with the format, timing and venue determined by the Premier League Board).
