Manchester City are prepared to end all interest in Harry Kane if Tottenham refuse to sell the striker this month.
The 28-year-old has been named in Tottenham's 25-man squad for Thursday's Europa Conference League play-off against Portuguese side Pacos de Ferreira.
Under UEFA rules, Kane would still be eligible to play for City in the Champions League if he features against Pacos de Ferreira.
Nevertheless, Kane's inclusion underlines Tottenham's stance that their star man is not for sale.
The Daily Mail says City are yet to improve upon their £100m informal offer to Spurs earlier in the summer. Spurs chairman Daniel Levy values Kane at a minimum of £150m and will not entertain offers south of that.
As it stands, City are unwilling to match Tottenham's valuation, though they do intend to make an improved offer before the window closes at the end of the month. And City chiefs are ready to tell their Spurs counterparts that they are unlikely to renew their efforts to sign Kane next summer if they fail this month.
Etihad chiefs believe they will get full value out of a mega-money swoop for Kane this transfer window with the striker's age becoming an increasingly important factor in any move next year.
Kane turns 29 before the start of next season, which would likely result in City cooling their interest in 2022.
