The Italian manager was delighted with his players and feels the Foxes' last-gasp draw against West Ham could prove decisive in the title race.
Claudio Ranieri hailed Leicester City's "blood, heart and soul" after Leonardo Ulloa's penalty snatched a last-gasp point for the Premier League leader against West Ham.
Jamie Vardy had scored and been sent off before West Ham struck twice in the space of three minutes to raise Tottenham's hopes of topping Ranieri's men.
But Carroll conceded a penalty in the last minute of stoppage time, which Ulloa converted to extend Leicester's lead over second-placed Spurs to eight points.
