And following the news for Stoke City boss Tony Pulis earlier on Sunday that Tom Huddlestone could still move to Stoke City on loan, Villas-Boas is positive he will be able to get bolster his midfield before the Friday deadline.
"The market can be frenetic in the last few days so anything can happen," Villas-Boas told Sky Sports.
"We are still looking to strengthen our squad with a midfielder so let's do the deals that we have to do."
In other transfer-related news, Villas-Boas says he would be happy for Michael Dawson to stay at Tottenham, despite allowing his captain to discuss a move to QPR.
As yet Dawson has been unable to agree terms with the west London outfit, while reports claim Stoke City and Sunderland are also interested in the experienced centre-half.
Spurs fans sang Dawson's name during Saturday's 1-1 draw with West Brom and Villas-Boas is remaining level-headed about the player's future, adding: "At the moment Michael is our player and we are happy to have him."
