There was also this instance where Eibar were pressing all the way to CB's/Bravo and instead of clearing it, the team decided to play a quick but intricate passing sequence to bring the ball out of the back. When the ball got to Masch, he passed it straight to an Eibar player and ruined the sequence.
These might be isolated moments but the point is that Eibar had literally around 2 spells of pressing high up the pitch for a semi-lengthy period of time, both of which showed cracks in Mascherano's composure under pressure. He's fully functional in games like Ajax/Eibar when teams get tactically dominated and pushed back to the point where they can't press/attack in numbers. However, that isn't the case with a team like RM who are looking to punish us with a swift counter at any moment.
