According to a report from Spanish media outlet AS, West Ham are prepared to spend €30 million (£25.6 million) on Athletic Bilbao centre-back Unai Nunez.
And the 22-year-old would be an absolutely sensational signing for the Hammers.
West Ham are desperately short in central defence.
Angelo Ogbonna is on the wrong side of 31, whilst Winston Reid is clearly not trustworthy from a fitness perspective.
The jury is also still out on Fabian Balbuena.
The Hammers need to bring more quality and youth into their defensive ranks in January. And Nunez would be absolutely ideal.
Standing at 6ft 1in tall, the Spaniard isn’t the tallest of central defenders. But he is an incredible reader of the game.
Nunez also has exceptional positional sense, is fairly quick along the ground, and those two things more than make up for his lack of height and aerial prowess.
The Athletic Bilbao defender clearly has what it takes to go on and become a truly elite centre-back in the game. And for just £25.6 million, West Ham cannot afford to miss out on him.
Bringing Nunez to the London Stadium would also buck the worrying recent trend whereby the Hammers have been signing ageing players well past their best on extortionate wages.
The 22-year-old Spaniard is a real top class player in the making, and he could totally transform the way in which West Ham set up as a defensive unit.
