A good learning experience for Duncan last night.
United were so much in charge in the first half that he didn't really get the opportunity to test Luke Shaw's defensive credentials, spending a lot of the time having to defend as United totally dominated. He created a great chance straight from the kick off at 3-0 with a fine run through the inside right channel but a woeful first touch by his colleague led to the ball going straight to the keeper.
Having been so outclassed in the first half, the Black Cats responded well in the second half & Duncan, who no longer had a £30 million left back to contend with, started to see a fair bit more of the ball, leading to some trademark runs & going close on a couple of occasions.
Full credit to United, they were outstanding in the first half & Sunderland deserve praise for sticking with it after the break. It wasn't an easy game for Duncan, but he still managed to have a positive impact & was always Sunderland's most likely creative threat.
