“Nothing has been concluded yet; we are still talking so I hope it goes well," Lawrence told Oyerepa FM.
“I have been speaking to coach Kwesi Appiah and [assistant Ibrahim] Tanko but it [the engagement] is not confirmed."

“You remember what happened previously. To make sure it doesn’t happen again, I want to finalise all [details] before I come down," the Jamaican noted.
“Let’s hope for the best because I am ready to contribute my quota to help Ghana achieve its target in the competition."
Ghana have set their sights on winning the trophy to end a 37-year drought.
The Black Stars have been drawn against defending champions Cameroon, Benin and Guinea-Bissau in the group stage.
