Mauricio Pochettino hopes Son Heung-Min can hit top form to stop Tottenham signing another striker this month.
South Korea forward Son's goal in Wednesday's 2-0 FA Cup victory at Leicester was just his third goal in 21 appearances since his £22 million summer switch from Bayer Leverkusen.
The 23-year-old has been challenged to start living up to his billing as Spurs' third most expensive signing, with Pochettino reluctant to recruit a forward unless he finds someone boasting "the right profile".
"It was important for him to score against Leicester," said Pochettino of Son. "We want him to fight for a place in the starting 11."
Son could come into the equation for Saturday's Premier League trip to Crystal Palace, as Spurs aim to cope with the Selhurst Park side's physical and pacy threats.
Spurs continue to be linked to a string of strikers, with Barcelona's Sandro Ramirez rumoured to be among their targets.
Pochettino insists the White Hart Lane club intend to be hugely discerning in their transfer business, with England striker Harry Kane in top form and hopes high that Son can find his feet.
"I don't know why we would have maybe more opportunity to win the league if we added another striker," said Pochettino.
"I think that we have enough quality already. If we started the season happy with the squad we have, why now do we have to add new players?
"If we find the right profile and we are sure that it would help us improve the squad, we'd sign someone, but we are very happy with the squad we have."
