Per the source, Bayer Leverkusen will only sell Calhanoglu for an offer than matches their £21.4 million valuation and he still has another three-years left on his contract.
Spurs have been given a transfer boost following his agent Bektas Demirtas who confirmed that he has received offers for the 22-year-old.
Speaking to SPORT BILD Demirtas was quoted as saying: “There are always offers for Hakan, there are always enquiries.”
La Liga giants Atletico Madrid are also reported to be in the race for the Bayer star this summer.
Calhanoglu scored 11 direct set-piece goals in the Bundesliga alone establshing himself as one of the most feared free kick specialists in European football.
Man City boss Pep Guardiola described him – during his time in charge of Bayern Munich – as being one of the best free-kick takers in the Bundesliga stating, “Çalhanoğlu is one of the best free-kick takers in the Bundesliga.”
Calhanoglu already has a few years top-level experience behind him having enjoyed successful Champions League campaigns for Bayer and establishing himself as a regular call-up for the Turkish national team.
