Losing four players is frustrating for Ancelotti but he would not be put off signing another African player in the future.
He said: "I think that when they have to play for their national team, it's not a problem. It's like the European players.
"Every top player can go to the national team. It's not a problem for the Africans. It'll be a great opportunity for the young players now to show their quality. I hope they will do a very good job because I trust in these players."
"In January we have a possibility to work every week without matches (in midweek)," he added.
"We have a possibility to improve our condition because, in December, we didn't have that opportunity to train.
"For this, I think we lost some physical condition. We had some injuries but I think that, in January, it will be better."
