I play with LFB, so that they're just concentrating on defending, and I tell them to stay wide. Yet they constantly seem to be running in from the middle whenever a ball comes down the wing (and they're not the quickest when it comes to getting over to cover). I play narrow, because my midfield triangle of DM and my CMs are my main creative outlet, but surely if play wider is set as a player instruction they should holding their position? Infact, 'Hold Position' is supposed to be one of their default player instructions. I've come to terms with the fact that they don't know how to/don't want to tackle, but they could at least be in the right place to maybe win the ball when it's sent forward.
