It's never a red and whilst I do get what you're saying, absolutely we need to think of Sonny. If we don't appeal it the very least I expect is a statement explaining that we have reviewed and don't see Son as being to blame and due to the moral reasons we don't want to get into something worse than what it is so we have agreed that wishing Andre Gomes well is more important than fighting Sons case.
I'm actually sitting here fuming that Son will get heat for this. Gomes actually elbowed him in the face minutes earlier which was far more reckless than a clip of the heels. The ending circumstances of no broken cheekbone anda broken ankle will tell a completely different story and that is hugely unfair on Sonny.
I say we fight it a shame anyone with half an idea about football can see Son did what any other footballer in the game has done, he just got unlucky that Gomes got caught a step after it happened with his footing. No way a red but Gomes' health also important. It's a tough one to call as Sonny will get heat and stick for this now and that comes from the referee buckling to the red.
