The 24 year old midfielder's lack of physical progress and mental frustration has caused Pochettino to believe a change of scenery may prove beneficial.
"He went to Italy now. They need to change a little about the atmosphere, he has strong links in Rome," Pochettino said.
"Not only do we believe it's important to change a bit his mind, if not he asks to finish his recovery time there. The club and the staff believe it was right that situation.
"We hope that after that period he will come again and be available to start training with the team.
"It's always difficult for players who spend a lot of time more than he believe, and with the energy of the team sometimes he is frustrated he cannot be involved today as it's only him out of the group."
"He has a special link with physios and doctors in Rome so thank you to Roma for opening the door to him and recover the player," Pochettino added.
"We hope that in a few weeks maybe he will be available again to be involved in the training session with the rest of the group."
