In fairness it was a fairly safe situation on halfway when cooper was about to receive the ball. Billy was chasing him down but the safe option was just to pump it forward
The keeper was already way out of his goal, about 10 yards from the centre circle. So his positioning was clearly aimed at getting the ball forward quickly.
It was a JOC v Villa type error, lacked concentration and execution.
What the keeper did was trying to put in some sort of tackle to bring billy to a halt... problem was that he was nowhere near the ball
Bielsa is cracking which his comments show. He should’ve just played it down and accepted that it was a series of errors
