Andre Villas-Boas thinks Tottenham did better in the transfer market than most of their main Premier League rivals.
Despite losing Gareth Bale to Real Madrid, Spurs brought in Roberto Soldado, Erik Lamela and Christian Eriksen among others.
And Villas-Boas said: "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.
"We are happy with what we have done in the transfer window, extremely happy.
"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."
As for Villas-Boas' opinion on Arsenal's capture of Mesut Ozil on transfer deadline day, for a reported £42.5m from Real, he added: "He is a wonderful, gifted footballer and in the end Arsenal paid heavily for a player of that dimension.
"It's a 50 million euro 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."
