The young winger is in line to make the matchday squad.
And Amorim said: “I’m really happy with him.
“I think he struggled a little bit with injuries, they did a very good job balancing his body.
“You can sense that he can manage more load during training, he has a lot of talent. But when they come here, they can sense the speed is completely different.
“So they need to spend more time with us to be prepared, because our trainings are hard.”
Meanwhile, on teenage striker Chido Obi, Amorim says last season's breakthrough came ahead of schedule.
“We didn’t have a team that we can put a young kid with 17, that he will not struggle, or will struggle a little bit,” Amorim explained.
“It was completely necessary to do that. We have the opportunity and we seek that opportunity for the kids.
“So (Obi)’s one of the guys but I think he started too soon. And sometimes it’s hard to deal with that, with the kids.
“Because they think that ‘I’m already here’. No, you are here for necessity, and we need to be careful also with that, with the kids.
“Even to call a kid for the first team, they need to behave really well. If you don’t behave really well, this connection is really important.”
