Spurs are reportedly stepping up their interest in South Korea centre-back Kim Min-jae.
Jose Mourinho is thought to be a big admirer of the 6ft 3in Beijing Guoan defender and Spurs reportedly had two bids rejected in the summer.
They are now set to go back in for Min-Jae with Chelsea rumoured to be circling.

Min-jae’s contract expires in December 2021 and his club are ready to cash in.
His sale would be an early blow for new Beijing boss Slaven Bilic who took over this month on a two-year contract.
Min-jae has three goals in 30 appearances for his country and won a gold medal at the 2018 Asian games.
He moved to China in January 2019 from Jeonbuk Hyundai Motors after winning back to back K League titles in his homeland.
Mourinho was critical of his side’s defending after the 1-1 home draw with Fulham this week, but insisted he was “not expecting” the club to be busy in the transfer window.
