The Croatia international is being heavily linked with a move to Real Madrid, with the playmaker opting not to travel stateside with the White Hart Lane club.
The north London side have stated that their star is back to training at Spurs lodge.
“The club can confirm Luka Modric has returned to training today at Spurs Lodge. The coaching staff will now determine the remainder of his pre-season preparation,” a statement on the club’s official website reads.
Meanwhile, Andre Villas-Boas has confirmed that his attacking midfielder has been disciplined by the club and that negotiations over a potential sale will continue.
“The situation as it stands is that the player is under club discipline for not being present,” the Portuguese trainer told Sky Sports.
“There is close interest in him but we have to hold onto our values and our rights and at the moment the situation for Luka is that he is under club discipline.
“Unfortunately for him he’s going to have to be fined for the club for not being present.
“He’s a player who has offered so much for Tottenham so we also have a sense of respect for what he has done over here for us but the chairman feels the fact he is not present is not common professional behaviour.
“Hopefully the situation can be solved in either of two ways, those being that the clubs’ interest meets the demands of Tottenham regarding the player’s value or the player continues and returns to club duty.
“I’m not sure on the extent of the amount of the fine. Hopefully this isn’t a situation that won’t drag on for long.
“We don’t doubt his human qualities. We don’t know what kind of advice he is receiving,” Villas-Boas concluded.
