Manchester United have raised their bid for Everton defender Jarrad Branthwaite.
Last month, Everton turned down a £35 million offer from United for the England international.
Sources indicate the new offer is approximately £45 million, with potential additional payments contingent on meeting specific targets.
Despite this, BBC Sport understands Everton still values Branthwaite higher than the current offer.
Branthwaite, noted for his performance as a left-sided central defender at Goodison Park, contributed significantly as Everton avoided relegation last season, despite facing penalties for financial rule breaches.
United is actively seeking to bolster their central defensive options and has been engaged in talks regarding Bayern Munich's Matthijs de Ligt, who is currently playing for the Netherlands at Euro 2024.
Following Raphael Varane's departure, negotiations with veteran Northern Ireland center-back Jonny Evans for a new one-year contract remain unresolved.
Additionally, uncertainties surround the future of Sweden international Victor Lindelof, who joined Carrington for the start of pre-season training on Monday.
