The Spurs boss is aware of the striker's recent improvement and believes Paul Lambert deserves praise for his management of the situation.
The Tottenham boss said: "He has been outstanding, for sure.
"He has eight goals so far. I think he is surprising everybody. To his credit he has come up strong. He has strong competition from Bent.
"I think Paul Lambert was courageous in his decision to keep on persisting with a player that he got so well in the transfer market so credit to them. But it is good to see him up there."
