Agreed. You only have to look at how Liverpool do it. Firmino drops deep, which draws defenders out and creates space for players running beyond etc.It’s more basic than that, and that’s what your missing. Football is a simple game, and movement and space wins the majority of games. There are holes everywhere and he’s doesn’t exploit them, drop deep pick it up, and draw a defender out. The space is then exploited. If the defender doesn’t go with you then you have the space, you can double up and have the advantage.
But he doesn’t, he stifles the attack, unless he’s given space by the opponent he won’t be effective. Its been proven over 2 years. And that’s the issue.
His reluctance to do this means Gomes or another midfielder won’t be encouraged to run beyond him and the striker to get on to through balls.
