West Ham boss David Moyes is expecting big things from January signing Jarrod Bowen.
Moyes said: "I have been pleased with what I have seen from Jarrod at the moment.
"He's come in and settled in very quickly, he's looked very sharp in training.
"He's obviously had loads of games, it's not as if he's short of match practice or match fitness in any way so I have been pleased.
"But I am also wary of putting the boys in too quickly. I have had lots of boys from the Championship in the past and I think it's important that you put them in at the right time, the right moments, at the right time and we will just take our time and see when it's right for Jarrod."
Moyes remained tight-lipped when asked if Bowen had done enough in training to earn a start against City but added: "He is a talent. We need goals, he can do that. I am also very aware that we don't need to put pressure on him too quickly."
