Andre Villas-Boas believes Tottenham's summer recruits will make more of an impact than the additions made by Arsenal, Manchester United and Chelsea during the transfer window.
Arsenal's club record signing Mesut Ozil is expected to make his first Premier League appearance against Sunderland on Saturday, and Villas-Boas admits the German adds a new "dimension to the Gunners' line-up.
Although he expects stern competition for a top four finish, the Portuguese boss insists his club had one of its most successful transfer periods in recent history and have an edge over their rivals.
"All of us have done good business in the transfer window, but Manchester City and us maybe a little bit more than Manchester United, Chelsea, Arsenal and Liverpool," he said. "We are happy with what we have done in the transfer window, extremely happy. Arsenal did a great least minute coup with Ozil but they will be as competitive as they were before.
"He is a wonderful, gifted footballer and in the end Arsenal paid heavily for a player of that dimension. It's a €50 million transfer for a number 10 that nobody has any doubt over his ability. They have lots of players for that position also but they have become even stronger with Ozil."
Despite the loss of Real Madrid's world record signing Gareth Bale, Villas-Boas is confident Tottenham are well poised to go one better than last season's fifth-place finish.
"This is a squad with great potential which has the ability to achieve our objectives that we couldn't last season," he added. "At the moment, we are trying to do that -- to put these players together and find a style in our play that brings out the best potential of each individual. That is the main objective.
"What we have improved on from last season is the individual quality we have on board and all the players are striving with big motivation to achieve it [Champions League football]."
Spurs will be hoping to recover from the narrow defeat to Arsenal a fortnight ago when they host Norwich at White Hart Lane on Saturday.
Villas-Boas believes the derby defeat will provide added motivation for his charges.
He said: "That is the only thing we can do. The frustration was big after the Arsenal game because we had an opportunity to continue our perfect start to the season, and get a win over our rivals, but we didn't create enough clear cut chances in that game even though we had lots of possession. We wanted a result there.
"The players have come back here now looking ambitious to get the result we need and hopefully they can step up their game so the team can do exactly that."
