With subs, you have to remember Bielsa believes if plan A isn’t working plan B is to try harder to make plan A work. When he subs a player it’s because he believes that’s the part failing. Dallas might look like he isn’t doing what you want him to but it could be he is doing exactly what Bielsa expects. I’m not saying I agree with Bielsa and his subs but it’s his method, he likes the like for like subs hence we never saw Bamford and Nketiah together.
Too much huffing and puffing and not enough quality. This season will pan out like last season without some additions that can improve the first team. Team lack a bit of sharpness.
