Only watched from the 40th minute. Think the U21 are a skilful team, most of them have a very good first touch and pass the ball with composure. A common weakness is often physical attributes and I think they could move more and better off the ball, not just come short for it, which they do.
Gilmour and Brooks are good ball players, as is Reed of course. Brown the left back has Geary-like enthusiasm, as has Charlesworth who played right back in the first half. Jo Cummings played right back in the second half, and I think he looks very promising. Unlike most of our players he's big and athletic, but also decent on the ball, put in a couple of good crosses after beating his man. Hard to see what he's missing, maybe he looked a bit lethargic a couple of times, but nothing he can't work on. Oseni at centre half looked decent to me. Ndjoli was ok, but didn't find much room to run into and his touch wasn't always the best. Ighoul put in a great cross just before he went off and looked a creative player.
From what I saw Palace defended quite deep and tried hitting us on the break. We found it difficult to find room and to play with high tempo. We still had three or four big second half chances and should be disappointed about not scoring.
