Ghana coach Milovan Rajevac has sent out the rallying cry to his players after the loss of influential midfielder Michael Essien dampened team spirit in their World Cup camp.
The Chelsea ace was ruled out of next month’s tournament on Thursday because of a knee injury he suffered six months ago.
Black Stars players were downcast after news emerged of Essien’s absence and the Serbian manager admits it is a blow to their aspirations.
"I am really disappointed that Michael Essien will not be at the World Cup for Ghana as a player," a broken Rajevac said.
"He is an important player on and off the field but we can't use him this time.
“Essien brings lots of advantages; he brings so many things to the team and always gives us options.
"It's most unfortunate. But I hope and believe that the other players would give off their best.â€
Despite the absence of Essien, the Serbian manager says unity and hard work will make the Black Stars prevail in a difficult tournament.
"We want to achieve with this team and must work hard. We will focus on the task ahead and hope we have a good World Cup,†the Serbian said.
“I hope the past experiences with injuries, though unfortunate will help us stay united and fight for each other."
Ghana will play Serbia, Australia and Germany in Group D of the tournament.
