The 29-year-old has yet to make an appearance for the White Hart Lane outfit this season, with Roberto Soldado preferred in the Premier League while Jermain Defoe has shone in the Europa League.

"Obviously every player counts for us," said Villas-Boas after the Goodison Park stalemate.
"We have Defoe on eight goals, Soldado on six. Sometimes we start with a 4-4-2, then that can change to a 4-2-3-1 with one striker up front, so there is competition for places and you have to try and break your way into the team.
"No matter how hard you try the others are trying just as hard as you. So you have to be patient and wait for your opportunity whenever it arises. I think that is the nature of any top club in the country.
"You look at [Manchester] City who have four strikers. Two of them play, two of them sit [on the bench]. It's no different for us, you have to wait for the opportunity."
Tottenham's 0-0 draw away to Everton leaves the club fourth, but level on points with Chelsea and Liverpool who occupy second and third.
