Chadli could be on his way out of White Hart Lane, a report claims.
With Andros Townsend let go in January, it is unlikely that another winger would be allowed to depart without a replacement being lined up.
With that in mind, here's three like-for-like upgrades for the 26-year-old.
Anwar El Ghazi
At 6ft 2in tall, and of Moroccan descent, you'd struggle to find a player more like Chadli than El Ghazi. However, the 21-year-old has all the potential to surpass the Belgian one day, and there are few better managers than Pochettino to ensure that that happens. The 11-goal forward has long been linked with Jurgen Klopp's Liverpool, but if the Reds fail to qualify for next season's Champions League Spurs would have another advantage. The Lilywhites boast a strong ex-Ajax contingent, which could also sway the 21-year-old's decision making.
Signed by Bayer Leverkusen as a 17-year-old, Brandt wasted little time establishing himself among the seniors. The Germany Under-21 star made his debut two seasons ago - as a replacement for Son Heung-min, in fact - and has barely looked back. This season has been by far his best yet, though, scoring 10 goals and assisting seven in 41 appearances. Like El Ghazi, he's the right age for a Pochettino signing (20) and, as Son's signing proved, could be available if the price is right.
Far shorter in stature - at 5ft 4in tall - but arguably the most explosive of the three in attack, Insigne's capture would be a real coup for Spurs, with Arsenal supposedly keen. The Italy star, who's scored 13 goals and made 11 this season, has helped deliver Champions League football to Napoli once more. However, the Premier League's vast riches could lure him to White Hart Lane. Unlike the others, though, the 24-year-old would likely command a regular starting place, which Pochettino may be reluctant to guarantee.
