Some rules are there to be broken.
And when Lionesses boss Phil Neville saw Wales star Kayleigh Green in agony with cramp he surely thought he was doing the sporting thing by helping her out.
Instead the former England and Manchester United defender was ordered to stop by a gesticulating fourth official from Fifa.
In the end, Neville might have been more frustrated by Wales holding on doggedly for a 0-0 draw in this World Cup qualifier at St Mary’s Stadium, Southampton.
But the incident nine minutes from time is the type of moment that leaves fans, players and managers so irked by the interpretation or inflexibility of some rules.
Neville only needed to step a few yards onto the pitch to help Yeovil midfielder Green.
And he seemed to be doing a good job, bending her toes back to ease the pain in her upstretched leg.
But he was made to halt the treatment – and was guided back to the dugout by the Fifa official.
Meanwhile, Wales keeper Wales keeper Laura O’Sullivan was outstanding in a solid defensive show from the visitors.
But England struck the bar through Jordan Nobbs and, with a game in hand, are just a point behind the Welsh in Group A.

Neville told BBC2: “It went how I thought it would.
“We didn’t play well in the first half and we showed no patience.
“We were a lot better in the second half but we didn’t put the chances away. We kept them hemmed in.
“Mel Lawley came on and brightened up the game. We got the ball out wide but we didn’t have the quality of the cross in.
“Full credit to Wales, they sat deep and nullified our threat.
“A draw was what they came for and what they got.”
