Manchester United have made an improved £43million offer for Ajax defender Lisandro Martinez in a bid to beat Arsenal to his signature.
The new offer is £5m more than their last proposal and is close to Ajax’s valuation.
The Ajax board will consider the offer today mindful Lisandro has already asked to be allowed to make his dream move to the Premier League.
Ajax had already been bracing for new bids after United and Arsenal both offered around £38.5m for the Argentine - though the Eredivisie club were holding out for more after Martinez's brilliant season.
He started 23 times in the league under Ten Hag to help them win the title and played 37 games overall - scoring once and even providing three assists.
Last week, Ajax directors Klaas-Jan Huntelaar and Gerry Hamstra were in London to discuss the original deal with United - who matched Arsenal's £38m bid but offered a structure that guaranteed them more cash.
But now United have caved in to Ajax's demands and stumped up more cash as they look to wrap up the deal and convince him to move to Old Trafford rather than the Emirates as they prepare to embark on a pre-season tour to Korea.
Martinez has asked to leave the Eredivisie club and is keen to try his luck in the Premier League.
While respectful of what Ajax have done for him, he does not wish to let the opportunity of a move to the Premier League pass and staying in Amsterdam next season is not an option for him.
He has told the club that reaching an agreement soon, with either United or Arsenal, will be the most beneficial solution for all parties.
Arsenal have had two offers rejected with their last, coming in at £34m plus add-ons up to £38m.
United countered with a £35.3m plus guaranteed add-ons to £38m but have the added pull of coach Erik ten Hag, who struck up a strong rapport with Lisandro during his tenure with the Dutch champions.
The Red Devils have already snapped up a player from the Dutch league - left-back Tyrell Malacia, who joined in a £13m deal from Feyenoord.
Ten Hag is also chasing another player from the Eredivisie and his former club Ajax - with forward Antony a target for his United revolution.
Sportsmail reported last week how Ten Hag rates the winger highly having worked with him for two seasons and he is eager to bring him to Old Trafford.
However, United feel that it will be difficult to do a deal as Ajax's valuation of £70m is seen as too expensive.
