The model makes West Ham 43% favourites here. Southampton carry the 29% upset.
Southampton have won three of their last five; West Ham have taken 7 points from their last five. Form gives little away going into this EFL Cup tie.
xG explained: Expected Goals measures chance quality. 1.5 xG = a side typically converts those chances into 1.5 goals. Outscoring xG = running hot, possible regression risk.
Southampton create chances worth 1.8 a game (and give up chances worth 1.2), leaving them +0.5 a game on the balance. West Ham create 1.2 (giving up 1.4) for a balance of -0.2. The underlying numbers clearly favour Southampton. They're creating better chances AND giving up fewer good ones.
Goals are a tough one to call here. Southampton are scoring 1.6 a game (1.6 of those at home) and West Ham manage 1.6 (1.6 on the road). Add it up and it's basically a coin-flip whether we see three or more, we make it 58%, so there's no strong lean either way on the goals line. Whether both teams score is a genuine coin-flip, and we make it 55%.
In the last 10 meetings: Southampton have won 2, West Ham 4, with 4 draws. These fixtures average 2.2 goals per game. 4 of the last 10 produced 3+ goals. Recent results: West Ham 1-1 Southampton, Southampton 0-1 West Ham, West Ham 1-0 Southampton.
