Fifa need to do more to check the safety of football boots following a number of serious injuries says Professional Footballers' Association chief executive Gordon Taylor. "Hybrid" boots combine metal studs and plastic blades which can become sharp. Last month Wayne Rooney missed two England matches with a gashed head. "We live in a very litigious world" said Taylor. "If a player had a bad injury that left him disabled then there could be [legal] consequences." It was the second time Rooney had been injured in such fashion after he suffered a leg injury last year which Taylor says was "very near to a main artery". Taylor now wants the sport's world governing body Fifa to introduce a proper testing method for the boots' safety. "The issue [with the boots] was highlighted when you saw the extent of the damage to his [Rooney's] head near his eye" Taylor said. "But this is also something that affects youngsters playing in parks. "Five per cent of all injuries are down to cuts attached to boots. It's not a high number but they can be very serious. So we need to do something about it.
