I appreciate that they have practical and financial benefits for clubs.

However, games are never quite the same when played on them and they cause more injuries, especially to knees and ankles, than grass and, in my view, they should not be permitted in the top two divisions.

Good for training on, but some players have adverse physical reactions after playing competitive games on them. Definite injury risk, although you get similar problems on the old rock hard grass pitches and even with some of the thick lush grass pitches which can catch the studs when turning quickly.

Not a fan of them.

Can't remember where I was reading it recently, but it seems that environmentally they are a disaster, shedding microplastics all through their lifetimes, and then being impossible to dispose of in any eco-friendly manner.

OTOH, one of my wife's relatives is involved with Stenhousemuir, and he once took me through all the costs and income associated with their pitch.  Basically, it kept them afloat.
