There's no hard info that I've heard or anyone I asked, it seems once again that nothing could be pinned on anyone except our training/specialist rehab facilities - which are now being rebuilt - as they were deemed substandard by PL standards (which I admit I was shocked to hear); but of course, this is on the injury management side - the suspicion is still on our weaved pitches (we train on different pitches that mirror our own and others). But the evidence is still inconclusive, although I did hear of another club (that I cannot name) who is going to replace all their weaved pitches to natural grass again.
