We started the season brightly because nobody knew what to expect from us...now, several games in, other teams know our strengths and weaknesses. And it's simple, double up on Grealish and Ndiaye and half the battles won. Just be very physical with Beto and Barry, and don't let Gana and Garner have too much time on the ball.
Moyes needs to adapt and not fall into the Dyche trap of doing the same things over and over again hoping the result changes.
It would start with being more proactive in his substitutions and changing things up. Dibling getting the ball quickly and being asked to get that left foot cross in nice and early for Alcaraz to make a late run into the box. Or ensuring Grealish and Ndiaye aren't playing too wide so as to get overlapping fullbacks, which in turn will give them more freedom because the left and right back are forced to go out and mark the full backs. Etc.etc.
