Coming up against Arsenal, it would be a no brainer to see the visitors have large spells of possession and nullify
whatever little threat the home side may pose; but Johnson, playing as the Right - Winger, could initiate counterattacks with his deceptive pace and has the ability to deliver that final ball for the likes of Steven Fletcher and Conor Wickham — who could start upfront for the Black Cats against Arsenal, to finish off a goal scoring chance.
When the opponents look at Sanchez as their biggest
threat, they look to close him down and smother
whatever little danger he might pose, subsequently making things a lot easier for the players around the Chilean.
For kids, yes, they're still learning, and some mistakes and hurt feelings are going to happen in the course of learning, so I wouldn't advocate adults intervening for every
little squabble (like, two kids fighting over one communal toy, or arguing about what to watch on TV), but if there's a steady pattern of deliberate and premeditated bullying going on, then yeah, I'd step in, whether it's physical bullying, name - calling,
threats, cyberbullying, theft / extortion, repeated exclusion, or
whatever.
