Luis Fernando Tena spoke to the media following the forward's absence from the team's first practice sessions as they gear up to represent the country in the Olympic Games.
"His not being here is not a pretext. He has to go [to Europe] and sign some papers. He asked us to be there in order to fulfill his transfer from Tottenham to another team," the former Club América and Cruz Azul boss told reporters in Mexico City.
Dos Santos has long awaited his eventual transfer after four disappointing seasons at White Hart Lane. In that period, the bulk of his activity has come from loan spells to Ipswich Town, Galatasaray and Racing.
"He told us which team [he's signing for], but I'm not at liberty to say which," said Tena. "For us, it's much better that he's calm, for him to fix his contractual situation and come back, if not in his best physical form, certainly much better mentally now that he knows where he's going to play."
Suitors including Spain's Atletico de Madrid and Sevilla have been mentioned by various press outlets as potential spots for the former Barcelona player, with English clubs Liverpool, Swansea City and recently-relegated Bolton also being named.
Tena also referenced Carlos Vela and Jonathan dos Santos, who declined to heed the call for London 2012.
"With all due respect for those not here, I'm not sorry for them. We don't even remember it, actually," Tena finished.
