The French giants are believed to be keen to lure the England international away from the Premier league after being impressed by his buccaneering displays from the right-hand side of Spurs’ defensive unit.
PSG are currently without injured full-back Christophe Jallet, and see Walker as the ideal replacement for their star as they aim to maintain their push for domestic dominance.
Monaco have been interested for some time, with the Russian-backed Principality-based outfit having the financial clout to compete for almost any player in world football.
Walker is a regular starter and a key player under Tim Sherwood in North London, so it remains unclear as to whether or not he will be tempted by either club – especially with the World Cup looming.
However, the vast salaries both teams can offer may tempt him – particularly Monaco who may present him with a tax-free wage.
Meanwhile, Tottenham could lose summer signing Erik Lamela.
The Argentine – a club record £30m buy from Roma – is unsettled at White Hart Lane, and is keen to return to Italy.
