Bristol City boss Keith Millen fears he could lose Africa Cup of Nations hopeful Albert Adomah for six weeks at the start of next year.
Adomah completed a remarkable transition from amateur footballer to international debutant when he came off the bench to play for Ghana last Monday.
The City winger completed an impressive 13-minute cameo against five-time world champions Brazil after which Ghana boss Goran Stevanovic predicted Adomah had a "bright future" with the Black Stars.
Adomah looks likely to be named in the squad again for next month's Africa Cup of Nations qualifier against Sudan, as well as a possible international friendly with Nigeria.
And with Ghana almost certain to make the Africa Cup of Nations tournament proper, which takes place between January 21 and February 12 next year, Adomah is hopeful of making the trip.
Millen said: "It is an honour for Bristol City to have players good enough to play at international level. It means we are doing something right and that we have some great players.
"Albert is certainly someone I wouldn't want to lose for a month in the middle of the season, but I'd never stop a player going to represent their country.
"Ghana still need a point to qualify and Albert is not quite in their strongest XI just yet, so we'll see what happens."
Whether or not Adomah manages to win selection for the Africa Cup of Nations squad, Millen has paid tribute to his flying winger following his achievements of the past week.
Millen said: "Albert has to take a lot of credit for the way he has developed over the last 12 months.
"We knew he had ability when he signed for Bristol City and I know a lot of people were looking at him before we took a punt on him.
"He has learned so much about the game and has adapted to the Championship without too much fuss at all.
"That is the thing that really surprised me. It is not always easy to step up a couple of divisions, but Albert made an almost seamless transition soon after coming here from Barnet.
"There is still more to come from him because his enthusiasm for playing football is fantastic.
"He needs to keep his feet on the ground, but I can only see him improving."
