Tottenham are refusing to meet Porto's asking price for Luis Diaz.
The Sun says Spurs want Colombian star Diaz but will NOT pay Porto's asking price.
Portuguese reports say Porto are holding out for a release clause figure of £67million, but they will listen to offers of around £55m.
But that is still too much for Tottenham, despite boss Antonio Conte is desperate for reinforcements in this month's window.
Liverpool were interested in Diaz before backing out, West Ham made enquiries and Manchester United have been monitoring the 25-year-old winger.
Portuguese giants Porto have already shown they mean business.
They sold two players this month — winger Jesus Manuel Corona to Sevilla for £2.5m and midfielder Sergio Oliveira to Roma on a £1m loan fee with the option to buy for around £12m.
Conte has also declared an interest in Wolves' Adama Traore this month.
