Andre Villas-Boas wants Luka Modric's uncertain Tottenham future to be sorted out quickly after he was fined for his refusal to train and absence from the club's pre-season tour.
The Croatian, who wants to join Real Madrid, did not report for training on Friday and was not on the plane that left for Los Angeles on Saturday.
"Hopefully the situation does not drag on," said Spurs manager Villas-Boas.
"It doesn't help Luka and it doesn't help solve in any way the situation."
Modric, 26, has been fined two weeks' wages, about £80,000, for missing training and Tottenham's pre-season tour to the United States, although a club statement revealed he had returned to their training base at Spurs Lodge on Monday to begin preparing for the 2012-13 season.
The former Dinamo Zagreb midfielder has four years left on his contract although Spurs are understood to be prepared to let him leave for the right price.
Spurs are looking for a fee close to £40m, but Real's best offer at this stage is about £27m plus add-ons.
Paris Saint-Germain are also monitoring the situation and have the spending power to match Tottenham's asking price.
Villas-Boas added: "The situation is not dependent on Tottenham, it is dependent on the clubs who are interested in the player.
"It's the first time Luka has taken these actions. The chairman and myself have been very open with the situation by saying we are willing to listen to offers for the player, which is uncommon.
"We never doubt his human qualities but the club has to take action regarding a player who is missing on club duty and that's what we are doing.
"We have to hold on to our values and our rights and at the moment, the situation for Luka is that he is under club discipline.
"Unfortunately for him he is going to have to be fined by the club for not being present.
"He is a player who has offered so much to Tottenham so we have to have a sense of respect for what he has done over the years for us, but the chairman feels that the fact he is not present is not common professional behaviour.
"Hopefully the situation can be solved in one of two ways - the two ways being that the clubs interested meet the demands of Tottenham regarding the player's value, or the player continues and returns to club duty."
Villas-Boas said Modric would be a major loss if he leaves Spurs.
"He's good, very good. I tried to sign him last summer for Chelsea," said the Portuguese. "He will be a big loss.
"He's a player who can make the difference, who gives a lot of clarity to the play when the team needs it and who can play in several positions."
