Lets face it, shirt pulling is rife in the PL and referees are very selective as to who gets punished. However if someones shirt is ripped off the back, it makes it very difficult to ignore or deny.
To my mind, the game has become very much about influencing decisions and it seems anything that gives you an edge is acceptable. I would have no hesitation in doing the above because it would put serious pressure on the officials to do their job.
Ps I accept that the shirt maker may not agree, but I can guarantee that shirt pulling would stop very quickly in this scenario.
