2nd Sevilla goal https://gfycat.com/SophisticatedSoreGlowworm: Huge initial mistake by Can, Henderson has tracked his runner out wide and Can just doesn't fill in. From there you could argue that Lovren, Moreno and Gini should do better but I think that's stretching it, it's just a very nice touch and finish. From my perspective this is mainly Can's fault, for whatever reason he just isn't in position.
Interesting thing on that goal if you go back 30 seconds further (Let's start at say 71:00). First look at our shape. It looks very compact and our line is quite deep. This is pretty much as defensive as you will see us. Similar to against Arsenal we have a fluid 4 asymetric cube in midfield (Hendo Gini Can Firmino) and one player will step out to be the striker depending on position of the ball. When it goes left, Mane steps out. Right Salah steps out. Center Firmino steps out. Then retreat. This is forcing Sevilla to try and play through a compact shape. Where is the space we leave? Left side in front of Moreno (it usually is - it's our ambush point).
We are zonal marking clearly. It's option oriented zonal marking. This means we care only about the position of the ball. Where it could go to hurt us. We press the man on the ball when he enters our half. We stay compact but the shape is fluid allowing us to move in relation to where the ball is and making sure no space appears in the central area. It also allows for man marking of attacking players at the deepest parts of the shape (watch Matip & Lovren man mark while everyone else is zonal)
Okay now watch it forward to the goal a few times and ask what times we become uncompact - and why.
71:06 - Salah is central so Can moves right to press the ball while Salah gets back.
71:10 - Salah now in his position. Can still nearby walking. We are now not compact centrally but okay because Firmino isn't pressing the ball and is staying compact in front of Henderon & Gini
71:13 - Ball moves right now, Can starts jogging into position
71:16 - Ball right flank. Can still not close enough to Henderson but getting there. Still no problem. Mane & Moreno have their winger boxed in nowhere to go
71:19 - Big gap now between Henderson and Can. Pressure from Moreno sees Sevilla turn and play the ball back towards half way line.
71:23 - Gini steps out to press the ball. It's played left into the center circle. Can too far right. Big hole in midfield. But we are still okay as long as Gini moves back into his shape before a Sevilla player moves into that space to receive. Firmino starts moving towards the ball. Salah has dropped in as a RM again next to Can.
So up until now - We have only pressed when they enter our half. This allows us to remain compact. There is no space in behind so we don't need to pressure the ball any higher than that. Just stay in shape. Press when they enter our space. Push them wide. Compress tem against the line of the pitch to win the ball or force them backwards. This is easy.
71:27 Ball played from center circle just into our half to #17 in front of Can. Can steps out to press the ball. Ball is played backwards to 15 yards inside the Sevilla half to #4. #17 starts a move into the space Can stepped out of.
71:29 Can presses the ball alone into the Sevilla half. #17 is now standing in an ocean of space behind him calling the ball. Salah should tuck in now and fill that gap. Can should retreat because we aren't pressing in their half. Just stay compact. Stick to the plan. #4 passes the ball back into the center circle still 15 yards into the Sevilla half.
71:30 Can decides to press him as well now. Because why not. Still the rest of the team isn't pressing. Just Can.
71:32 Ball played back to #4. Henderson and Gini have adjusted to a flat 2 in midfield to cover for Can who is now caught behind the ball. Salah now needs to step forward to stop #4 progressing into our half leaving a space behind him to Henderson's right. This leaves #18 of Sevilla free to move forward on the right who is now in front of TAA who no longer has Salah's protection.
71:33 #17 Receives the ball in the pocket behind Salah to Henderson's right. Can starts his run back but is now 15 yards behind the ball. Can stops his recovery run still ahead of the ball. No idea why. He should be dropping into Hendersons space as he needed to step out to deal with this problem in Can's zone.
71:35 Henderson heads off the run of #17 stopping his progress. He turns and plays the ball sideways to #18. TAA needs to step up and deal with him in Salah's absence. Gini is moving across to protect zone 5 in front of our defence now as the lone center mid with everyone else on the right flank. He has an OCEAN of space to protect. Can jogging.
71:36 TAA presses #18. #17 turns and makes a run in behind TAA to receive a through ball. Henderson tracks the run brilliantly. Gini still out lone central midfielder. Salah ahead of the ball. Can too and still not moving into the space Henderson has left. Now walking.
71:37 #18 attempts through ball. TAA blocks. Throw in. Henderson is now effectively our RB marking #17. TAA next to the throwin taker. Salah too. Can standing level with the throwin. Still an absolute ocean of space between Gini & Henderson. Is Can winded from the press he shouldnt have made further forward? He's walking.
Okay so the ball is now out of play. Position reset and man mark near the ball. TAA needs to make it back to RB. Salah needs to mark the throwin taker once the ball comes live again. Can needs to make it back into his midfield position. Henderson is marking number 17. Bobby will move to mark any ball thrown towards defence. Gini needs to protect zone 15 in front of defence until the midfield gets compact again when Can gets in beside him. But he is standing stationary watching the ball.
71:39 Throwing taken quickly. Ball received in that ocean of space between Henderson and Gini when their striker drops deep to collect. Can realises whats happening and starts running back. Too late. Henderson also notices and leaves his man to close him down. Gini ball watching notices what happens and starts running back towards goal but Correa has already started running too behind him.
71:41 Striker received and turned. Henderson does well to close him down but didn't get goal side. Moreno - who has their right winger high and wide right - is playing very narrow next to Lovren. But still not narrow enough to prevent Correa. He is the only person who notices his run now and starts his own run to stop him. Lovren doesn't know whether to step out to the ball or drop off. Can has given up and decided to jog again. Gini isn't aware of Correa still. He's deciding to come across and help Henderson who cannot get goal side of the striker.
71:43 Lovren caught standing square undecided whether to press the ball or drop. Correa's running in behind him and the striker plays him through. Moreno won't make it across. Gini never makes it near to the striker either. Can still trotting back.
So that is pretty much the breakdown of the goal. If anybody can get a clip from the full minute from 71:00 - 71:50 you will see how we lose our compactness, why, how Gini has to play midfield alone rather than watch Correa. Honestly, we were totally fine up until 71:23 in that game.
