Tottenham's sporting director Damien Comolli has vowed the club will continue to pursue available targets until the transfer window closes in three days' time.
Spurs are currently waiting to see if Middlesbrough will accept their offer for England winger Stewart Downing but Comolli stresses the club will remain active until midnight on August 31 where they can.
Tottenham's £8m (?12m) offer for Downing was attacked as "derisory" by Boro's chief executive Keith Lamb but the north London side remain hopeful a deal can be brokered.
But if Spurs fail to land the player head coach Martin Jol has identified as their number one target, they will switch their attention to others capable of filling the left-sided berth.
Comolli confirmed they will remain busy in the market until the last possible moment if the right players become available.
"We will remain proactive until midnight on the 31st in the event of players becoming available who we feel will strengthen the squad," the Frenchman said.
"This will always be our objective but it is all about the availability of good players.
"We have been associated with many players during this period of intense speculation and where we have felt that comment is appropriate to distance ourselves rom unhelpful inaccuracies, we have done so."
Meanwhile England defender Michael Dawson believes their home defeat by Everton on Saturday left the squad with a feeling of déjà vu.
On the opening day of the season, Spurs were humbled by Bolton at the Reebok Stadium.
