Thomas Frank has praised the Lewis family for reaffirming their long-term commitment to Tottenham via a notable cash injection.

Earlier this month, £100million was pumped into Spurs and more money could yet follow as the club seek to fulfil their potential on the field.

That is good news for Frank, who oversaw a £125m spend on new players this summer during his first window at the helm, as Tottenham are evidently planning to spend a credible percentage of those finances in the transfer market.

Frank said of the Lewis family, who have continually insisted the club is not for sale since the departure of Daniel Levy: "First and foremost, I think it's hugely positive that the Lewis family is clearly showing their interest in doing everything they can to improve the club and back the club as they want us to be as successful as possible. I think that's a sign of it, that they are injecting cash into the club."

The former Brentford boss was also quizzed on whether Spurs could actually spend the entire £100m on one single player.

The club's most-expensive transfer to date - inclusive of add-ons - was the signing of Dominic Solanke - worth up to £65m if various bonuses are met.

"I don't know," replied Frank. "I think in this world, you get surprised sometimes both ways. I think for me, if you spend £10m, £100m or £150 million, for me, that's, of course, there's a difference in the amount.

"I think the most important thing is that we have a very good recruitment strategy. And we're very aware of what we are recruiting and what we want to bring in. Then it's about making smart decisions, so that's it."

There have been major changes to Spurs' infrastructure this week as the return of Fabio Paratici, now joint sporting director alongside Johan Lange, was officially confirmed.

Frank said of the Italian, whose 30-month worldwide FIFA ban formally expired in July: "I think it's something, of course, I've heard about. I don't know too much about the details but I know Fabio as a good guy from the times I've met him. I think he's got a lot of quality and I look forward to working with him."

The Spurs head coach also made it clear that neither Paratici or Lange are likely to sanction a transfer without his total approval.

He added: "I'll always have the final say. You know that but of course, in the end, it's teamwork."
