I don't mind the idea of Coady being used as a back up in the middle of those three defenders. He won't need to do anything really apart from throwing himself in front of shots (which he's capable of doing), holding the line (which he's capable of doing), shouting instructions (which he's capable of doing) and playing a simple pass to someone more creative (which he's capable of doing). He has a good character, despite his limitations as a player - so if Nuno feels he can offer something there, it keeps him away from the midfield positions where we have better players.
Fair play to Jack Price. I think he was one of the players that would have been in danger of being shifted on, but he appears to have impressed Nuno & the coaching staff and as others have said, he may suit this formation better and with actual footballers in and around him hopefully we'll see the best of him. Saiss/Neves/Price are very good options at this level - and I can understand why it's Evans that looks set to miss out.
I'm excited by Douglas. He just seems very considerate with his passing and positioning. A left back who can pass, overlap & defend. WHAT ON EARTH is one of them?! Plus his set piece delivery was superb.
Spiers was a little unsure on Boly and said he seemed "rusty". From the stream, I can't say I noticed him do much wrong. I think we've got a massive player (literally) there.
All in all, a pleasing display. Scoreline isn't important but it's nice to get off to a winning start & winning games of football breeds confidence - even if we were lucky in the end.
