The 23-year-old has made a miraculous recovery and will return for the showdown with the Premier League champions at White Hart Lane tomorrow.
Spurs boss Villas-Boas said: "I think there will be a fear factor for City. We recognise the impact this player has had for us this season.
"The run of goals that he is on can have that factor.
"It is good having key players around and players who have been decisive, especially in this last part of the season, is always inspirational for everyone. It is good to have him back.
"For him to be back so quickly speaks highly of our medical department and what they have done and the recovery of the player."
