Manchester United are in advanced talks with Athletic Bilbao over the transfer of Ander Herrera.
It is understood that United are prepared to match the £28million buyout clause in the midfielder's contract.
United are aiming to get the deal - which would see Herrera sign a four-year contract - done by the end of this month as the buyout clause raises to £32m after July 1.
Herrera was the linchpin of Bilbao's midfield last season as they finished in an impressive fourth place in La Liga.
He scored five goals in the campaign, but despite being one of the most impressive performers in domestic football, he is yet to break in to the Spain team.
David Moyes was reportedly targeting Herrera, 24, last summer, but failed to land the central midfielder.
His successor as Manchester United boss, Lous van Gaal, looks set to pull off the deal as he begins rebuilding the squad.
Herrera was born in Bilbao but came through the ranks at Real Zaragoza before joining his hometown club in 2011 on a five-year contract.
