Arsenal midfielder Ainsley Maitland-Niles could be rushed into Roma's squad for Sunday's clash with Juventus.
Maitland-Niles has been registered with the Lega Calcio, joining Roma on-loan to June without a permanent option.
He has been in Rome since Wednesday, when he underwent his medical.
Sky Sport Italia says he is ready to play and could start for Roma against Juventus.
The 24-year-old played his last competitive game on November 20 in Arsenal's 4-0 defeat against Liverpool.
