Spurs have held talks with Crystal Palace over a move for Eberechi Eze as they look to fill the gap created by long-term injuries to James Maddison and Dejan Kulusevski.
Asked if Eze is the kind of player Spurs are looking to sign before the transfer window closes, Frank responded: “We are looking of course in the market.
“Not only for 10 position but just to see if we can strengthen the squad. The players we are looking [at] are only players we think can improve the squad. That's the right thing we want to do. If we can pick the right player and it fits, then we will do something."
It has been a relatively quiet summer so far for Spurs, with Mohammed Kudus the major signing last month and Joao Palhinha arriving on loan from Bayern Munich.
Frank emphasised the work that is going on behind the scenes to further strengthen, but pointed to Wednesday’s UEFA Super Cup defeat to Paris Saint-Germain as evidence of how competitive the current squad can be.
“I think there’s a lot of good players. I think we saw a team that was very, very, very competitive, and on any other day we would have beaten the best team in Europe.
“Of course, we want as strong and competitive squad as possible. I know that Daniel (Levy), Johan (Lange) and Vinai (Venkatesham) are working night and day, and they have, by the way, been working night and day the last, whatever, six, seven, eight weeks.
