Wanner was extraordinary. Easily Heidenheim's best player, creative and tricky, consistently able to take advantage of Chelsea playing two non-DMs in the double pivot. Had one great chance where he basically wriggled through multiple defenders and got a great snap shot off (Jorgensen made a very good save on it).
Heidenheim were very open, very offensive. Chelsea played a pretty offensive XI (Caicedo didn't travel, and so the double pivot was Dewsbury-Hall and Casadei, both of whom are 8s), which left a lot of space for Heidenheim to work with. But Heidenheim were also very accommodating in providing space for Chelsea to work with! The final shot (on target) tally was 16 (11) to 17 (9). Major issue for Heidenheim was simply that they could not figure out how to adjust to Chelsea's high line. Even when defending deep, Chelsea hold a firm line on 18 yds (they do it in the league also, there was a great write-up about it in The Athletic recently). Heidenheim were caught offside 6 times. Multiple goals disallowed on offsides that were not even close. It was almost strange.
2-0 likely a harsh result on Heidenheim - there's a reason why Jorgensen was given MOTM (the first time this season he's actually seized an opportunity to look good and potentially displace Sanchez) - but the Chelsea win was fair. It just simply should've been, like, 5-3 instead of 2-0.
