Netting in front of away fans could be a permanent fixture at Manchester United after a smoke grenade was hurled at disabled supporters.
The away section at Old Trafford is directly above the area for disabled fans, who in the past have been struck by a missiles including coins, urine-filled bottles and umbrellas.
Now, after a smoke grenade landed next to a number of wheelchair-bound spectators at this season's clash with Wolves, United officials are examining ways to keep fans safe.

Following complaints, United installed high netting for the Champions League fixtures against Juventus and Young Boys to great success.
