The Premier League side parted with £23million last August to sign Serge Aurier and made a repeat payment in January to grab Lucas Moura. They look set to make it a hat-trick with Layvin Kurzawa now on their radar.
According to reports in the Daily Mail, Spurs are looking to capitalise on the fact PSG will have to sell players in order to comply with FFP rules and have made the France international a top summer target.
Spurs boss Mauricio Pochettino has two of the best left-backs in the Premier League at his disposal in Ben Davies and Danny Rose. But the latter appears to be set for a move away when the season comes to an end following an explosive interview last summer in which he criticised Tottenham's pay structure and recruitment policy.
Both Manchester clubs are keen on Rose and, with Davies' form this term so impressive, it's unlikely Spurs will fight too hard to retain the England international's services if a fair offer is received.
Ryan Sessegnon is reportedly a Tottenham transfer target – though he has been linked with just about every Premier League club this season. However, he might opt to stay with Fulham for another season meaning Pochettino and the recruitment team may decide to cash in on a full-back and spend a percentage of that on someone currently plying their trade in Paris.
It's possibly the best place to pick up value for money buys with PSG in a predicament having spent heavily last summer. But how does Kurzawa compare to Davies and Rose?
Comparing Kurzawa to Rose and Davies
Unlike many other teams, Spurs use their full-backs as wingers. They're there to keep the width and stretch the opposition and it's why the graphic above looks at attacking stats as opposed to defensive ones. What they can do in the final third is what they'll be judged on.
Kurzawa leads the way for pass accuracy, 6.2 per cent above nearest rival Rose. But, aside from that, he's trailing the two Spurs players in all of the other categories.
Davies, who has been a creative force this term, leads the way for open play key passes as well as expected goals assisted per 90. Kurzawa trumps Rose in the latter stat but the Manchester United transfer target gains grounds in the former.
The PSG left-back completes 0.88 dribbles per 90, 0.30 more than Davies but 0.42 fewer than Rose. The teams they're playing in and the opposition they come up against need to be taken into account for full context, though.
However, it's clear when looking at the graphic Kurzawa wouldn't cause Pochettino to bench Davies. But he might do a job replacing Rose as the rotation option. Spurs, with title aspirations next season, should be looking at first-team upgrades and not squad fillers, however.
Should they gamble on the Frenchman fulfilling his early potential under Pochettino or simply look elsewhere? There are some big decisions to make for those in charge of recruitment at the club.
