Courtois is convinced Batshuayi has the ability to prove himself Chelsea class.
“Michy is young and he needs to be given time. Not every striker will have the same impact at the same time.
“But he is doing well, he has scored some important goals. Obviously, he has to keep on working and doing what the manager asks of him.
“But sometimes he has played in games where as a team we haven’t had enough possession or we can’t reach him well enough.”
Courtois also spoke of Batshuayi’s strop during defeat at Crystal Palace.
He added: “After Crystal Palace, people criticised him and that is not easy. He showed a lot of spirit to come back from that.
“When he came off against Palace, I don’t think he was reacting towards the coach as some have made out, but he was just disappointed with his game, that he couldn’t make an impact.
“So it is good that he worked hard during the following week and tried to fight again. He had another opportunity against Watford, scored twice and that’s important.”
