Ferguson and United chief executive David Gill have been wrestling with the Tevez situation for months, pondering whether to spend STG25.5 million ($NZ67 million) to turn the Argentine forward's loan deal into a full-time transfer.
Ronaldo, meanwhile, had said repeatedly he was staying at Old Trafford but threw doubts into everyone's minds after Wednesday's 2-0 loss to Barcelona by saying "I don't know" when asked about his future.
Ferguson, fuming about his team's poor performance at the Stadio Olimpico, wasn't asked about either player's future after the game but those questions are bound to follow as soon as the team lands in Manchester.
Although admitting that Barcelona was the better team on the night, Ferguson tried to sound upbeat after winning the Premier League, FIFA Club World Cup and League Cup in one season.
"We've done well," he said.
"It has been a long season - that was our 66th game - and you've got to give the players great credit for the courage and resilience they've shown throughout.
"Now we have to come back stronger. That's what we do at this club. We have to accept it, we've been beaten by the better team. Next season, we'll be stronger." Whether that's with Tevez and Ronaldo is another matter.
Gill said before the game that United considered the fee demanded by Tevez' owners as too high in the light of the current economic climate and the fact the club has already spent 10 million pounds taking the star on loan. Yet there were reports on Thursday that Chelsea was considering a bid of 43 million pounds for Bayern Munich's French star Franck Ribery.
United makes enough working profit to pay the Tevez fee but most of that cash goes to pay off the interest on the borrowing that US owner Malcolm Glazer needed to buy the club four years ago.
Tevez is a huge favorite with the United fans. Despite Ferguson's amazing record of 25 major trophies in 23 years at Old Trafford, some fans may question his judgment if he lets Tevez go and possible play against United next season.
Until Wednesday night, the Ronaldo situation seemed clear.
The Portuguese star, who last year said openly he would like a move to Real Madrid, has been saying for months he wanted to stay at Old Trafford.
By raising new doubts about his future, he appears to have left the situation in limbo during the summer break. It could be that he really wants a move or is seeking a better deal with United.
