The striker did not report for pre-season tests on Monday and it later emerged he was still on holiday in Florida as he tries to force a move to Manchester City.
He is due back at the club later this week, and is set to be fined. Spurs are determined to keep their star man, who has three years left on his contract, and with no City bid on the table Kane’s options are limited.
Nuno, who is yet to speak to Kane, intends to keep the business in-house.
“We have not been asked (to arbitrate) but obviously Harry is one of our members and we’d love to be able to help,” he said.
“But in the end, we are here if and when required. It’s important that they (players) know we are here and how we can support them. We’re not here to force anyone.
“What I have learned over time is you need to be careful about how you make an assessment without knowing the details. Sometimes when you see a building from the outside it is one thing and when you’re inside the building it’s a different thing.
“So in general, be very careful about issuing an opinion without knowing the details. I have seen how people have written stuff (about me) and I was like ‘well that’s not exactly the truth’.
“I prefer not to have an opinion on a situation that I don’t know in depth.”
