You can't be serious brother.
First goal: This was possibly the worst of the lot. Lindelof starts this goal by playing an awful ball to Eriksen in our own half. When we recover and defend, Lindelof sees Isak, but he gets done by thinking Trippier is going for a cross, so drops back all the way into our own box. It gives Isak time to recover from a bad touch and find Tonali.
Second goal: There's only one option for Murphy, which is easy to defend if Lindelof had any awareness and wasn't jogging.
Third goal: Barnes runs past him. How he shapes his body and turns to defend here is pathetic. Doesn't even give himself a chance to foul.
That doesn't mean that any of our other plays covered themselves in glory for any of the goals (see Dalot, Yoro, and Amass for Newcastle's second goal), but once again he's one of the main culprits if not the main.
