Won't bore with all of last years full match stats, so I'll just update relevant ones.
Replacing relegated teams with promoted teams(alphabetical order) :
Stoke - Cardiff
Swansea - Fulham
West Bromwich - Wolves
Round 8 Comparisons:
Corresponding :
+3 pts, -2GF, +2GA, -4GD
Round by Round:
+1 pts, =GF, +2GA, -2GD
Although our GD is slightly worse this season, scoring less and conceding more, the corresponding comparison shows we have 3 clean sheets in both seasons, but this season we have managed to score in every match, unlike last season when we were held to 2 goalless matches (25% of games accumulated).
The good news is that over the last 2 seasons our best period arrives around round 16:
2016-2017:
Rounds 16 to 34, 19 games played: W16, L1, D2.
Longest season W streak - 9 games (Round 26 to 34)
2017-2018:
Rounds 15 to 32, 18 games played: W13, L1, D4.
Longest season W streak - 6 games (Round 27 to 32)
