Cristiano Ronaldo has declined to confirm whether he will retire from international football or play on after he was left in tears by Portugal's World Cup exit.
Ronaldo will be 37 when the next World Cup is held in Qatar and the Portugal captain would not give any clues as to his future plans.
"Now is not the time to talk about the future of players and coaches," Ronaldo said.
"We have a fantastic group, young and with a lot of ambition and for that reason I think the team will remain strong."
Santos had earlier told reporters on his talismanic forward: "Cristiano still has a lot to give to football.
"There is a tournament in September and we hope Cristiano will be with us to help the players grow."
Ronaldo helped Portugal to glory at Euro 2016 in France but watched much of the final from the sidelines after suffering an injury.
