The model makes Brentford 47% favourites here. Birmingham carry the 26% upset.
Birmingham are unbeaten in their last five; Brentford have taken five points from their last five. The momentum is with the hosts going into this EFL Cup tie.
Brentford are creating better chances than their goal return suggests (chance quality of 1.5 against 1.4 actual goals). They look due a few more. A concern for Brentford: they're giving up chances worth 2.0 a game over their last 5 (vs 1.6 for the season). The defence is creaking.
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.
Birmingham create chances worth 1.2 a game (and give up chances worth 1.2), leaving them 0.0 a game on the balance. Brentford create 1.5 (giving up 1.6) for a balance of -0.2. The chance quality on both sides is remarkably similar. There's nothing to split these two underneath. Brentford are creating chances worth 1.5 a game but only finishing 1.4. the underlying performance is better than the results show. Brentford's defence is giving up chances. Worth 2.0 a game over their last 5 vs 1.6 for the season. They're becoming easier to break down.
Goals are a tough one to call here. Birmingham are scoring 1.2 a game (1.2 of those at home) and Brentford manage 1.4 (1.4 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 53%.
Birmingham do it the hard way: only 1.2 a game up top, but a mean 0.6 conceded. They're a tough nut to crack: they soak up pressure and hit you on the break.
