"Everybody is happy with how Gideon played in the first week with the Chelsea academy," Essien told Ghanasoccernet.com. "I have monitored his performance from afar and I think he is capable of fitting into the academy and progressing to reach the first team.
"I am not saying this because he is from my country but because he is a talented player as people at the academy are saying.
"I am confident that if he is given a contract here he will develop into a world-class player for Chelsea and can also develop to help my country.
"I took him to meet some of the first team players and this experience has increased his desire to stay and I am confident if he is given the chance he will excel."
