The Monte-Carlo website is bilingual but it’s not word for word translated from French into English. In the English version it simply reports that RF accepted a WC… but in the French version it says a WC was reserved for Roger Federer until the last moment.
This is what the tournament director wrote on the official homepage:
"Several months ago I announced that Roger had not planned to take part as he had modified his clay-court preparation. But, knowing his attachment to the tournament, we never lost hope that he would nevertheless be there this year; we have been proven right and are very proud,” announced tournament director Zeljko Franulovic.
Good decision from Roger to take part in the tournament
I couldn't really understand why he skipped the tournament in his actual schedule. He had good matches there in the past.
