Leicester boss Sven-Goran Eriksson saw his side win 4-2 over Millwall as the Foxes remain unbeaten at the Walkers Stadium since the Swede took over in October.
Eriksson said: "This was a good win. Millwall are difficult to play against. They are very direct and always fighting for the ball.
"But we played good football and deserved to win, absolutely. We have made a good start to 2011.
"I still believe we can at least reach the play-offs. I want to take this club up to the Premier League and stay there."
Everton loanee Ayegbeni Yakubu, who scored on his home league debut, came in for special praise.
Eriksson said: "Yakubu is real class and takes a shot so quickly and goalkeepers are always going to have real difficulties with that. He will do very good for us."
Yakubu sees his future at the Walkers Stadium. The striker said: "I want to stay and win promotion. If we can reach the play-offs then we have a real chance."
Millwall counterpart Kenny Jackett blamed injuries for a defeat which ended their nine-match unbeaten run.
Jackett said: "We gave Leicester plenty of problems going forward, scoring a couple and missing a penalty, but you can't expect to take anything from a game if you concede four goals.
"But we have had to make lots of changes in defence with a lot of people out injured. But you have to take the positives and keep going."
And Jackett claimed the result hinged on Millwall defender Bertal Askou's straight red card for a bad tackle on Yakubu on 72 minutes.
Jackett said: "The sending off killed the game. We conceded a goal straight from a free-kick which followed and that made it 4-2.
"There was no way back and from then on it was just a question of damage limitation."
