The problem seemed to me to be players, with some exceptions, trying not to make mistakes or in a few instances trying too hard. Look at Esse and Drakes-Thomas. The former not prepared to take on a man whilst DT happy to give it a go and create something for the team. Zaha was always prepared to take someone on and lost the ball many times. It didn’t faze him. Esse seems scarred by the dressing down Glasner gave him at Liverpool and needs Sage to rebuild his confidence.
I think people are too critical of Ozoh. He was an exciting prospect at 18 but was hit by a series of injuries losing at least a year of development. Roy rarely showed confidence in young players but played him in Premier League matches. His cameo performance away to Man City showed that he is not a player to write off yet.
