For only playing together a few games the centre back pairing looks pretty good, yeah they are not perfect but compliment each other well and will improve. I thought Mercer had a decent first half, didn’t shirk a 50/50, good in the air but did notice he was caught out positionally a few times, Marshall has improved on last season. Reasonably happy with the defence also like the way Jacobs just slots in there when the full backs go past him and Doyle organises well. The keeper well he does worry me. Big strong lad like him needs to be commanding his box and coming for the ball to take some pressure of the defence.
