You must be positioned to see the ball as a goalkeeper. It's one of the first things you are taught as a goalkeeper, alongside having your feet planted on the ground when a player takes a shot, so that you can react in time. You have a player that is naturally going for the curler and you leave a section of the goal that your player has to cover, in this instance the first post. Varane made a few mistakes here:
- Standing too far away from the player, he has to be tighter
- Not showing him on the outside, on his weak foot
- Spreading his legs wide open
Onana might be at fault for the cross he did not get on time that could've been a goal of not for Licha, but for this, I dont blame him. There were at least 4 idiotic mistakes prior to this, like sending Maguire and Evans for a corner in the 95th minute, when it takes them 2 minutes to sprint back.
