Boss Claudio Ranieri has claimed Leicester's January transfer business is already over.
The Foxes chief insists he does not expect to make any more signings to aid their surprise Barclays Premier League title challenge.
Winger Demarai Gray signed from Birmingham for £3.75million and made his debut in Sunday's 2-2 FA Cup draw at Tottenham.
Leicester go back to White Hart Lane on Wednesday sitting second in the league but Ranieri said there are unlikely to be more arrivals.
"The transfer market is finished for us," said Ranieri. "I am only interested in my players and no-one goes away. Business is finished.
"There is no temptation (to make a big signing to push for the top four).
"You think with one big player we'll arrive in the Champions League? Possibly, but you can't be sure.
"Step by step we are building to try in the future to fight for the Champions League. Now this is a crazy league and we fight to achieve the maximum.
"There are three, four or five teams ahead of us. They are building and then slowly we arrive."
Spurs are four points behind Leicester in fourth, with the Foxes hopeful 15-goal Jamie Vardy will recover from a minor groin operation to play on Wednesday.
Ranieri will assess his players ahead of the game and insisted he needs to see them with his own eyes.
He added: "If the manager asked the players they always say they are okay, but it is not always true so I want to see with my own eyes."
