Agreed, but the board have played a big part in this as Pellegrino showed nothing in his portfolio to suggest he could do a job here, they tried to strike lucky again as they did with Poch and it has backfired massively.
Secondly, their reluctance to get shot of him when it was patently clear he was not up to the job is negligent to say the least, and to continue that stance is disastrous.
Yes Pellegrino is totally unsuitable and way way out of his depth, but the board hired him and in my book they should take the lion share of blame.
