The 63-year-old, who took over at White Hart Lane two years ago with Spurs bottom of the table on two points from eight games, last term led his side to a fourth-place finish and a Champions League spot.
And he thinks a couple more high-quality additions would help the north London club take the next step.
Quoted in several newspapers, he said: "I think Tottenham may be one or two big signings away from being a team that could win the championship.
"One or two players in the right positions - and I'm talking about two top, top players in the right positions.
"If we could go and do that I think Tottenham are a team that could win the championship in a couple of years."
