Tottenham are weighing up an approach for Everton defender Jarrad Branthwaite.
Their interest, which could be formalised as soon as this week, comes despite the Toffees telling suitors that Branthwaite is not for sale this summer.
Chelsea have been pondering over a swoop and Spurs were expected to test the waters, but David Moyes wants the in-demand England international to stay.
Manchester United saw offers worth around £50million rejected last year while Liverpool and Manchester City have also kept a close eye on the centre back.
Moyes is mindful of how important Branthwaite has become as part of a stubborn backline alongside James Tarkowski, Jake O'Brien and Jordan Pickford.
Indeed, he wants to keep the core of his defence together when Everton make the transition from Goodison Park to their new stadium at Bramley Moore.

But Branthwaite is said to be keen to make the step up to the Champions League and Spurs can offer it after beating United in the Europa League final last month.
Everton, who have the shadow of Profit and Sustainability Rules looming over them, are realistic and could consider substantial bids in the region of £70million.
However, Moyes is hopeful that new owners the Friedkin Group can resist any big-money approaches for the 22-year-old - if only for this summer.
Branthwaite made 32 appearances in all competitions last season despite being ruled out for the opening months of the campaign after undergoing groin surgery.
Spurs are now managed by Thomas Frank and on Sunday, they confirmed the permanent signing of young forward Mathys Tel from Bayern Munich.
Meanwhile, Everton are among the clubs showing interest in Lyon left back Nicolas Tagliafico, who is out of contract this month.
