Manchester United have made an improved £43million bid for Ajax defender Lisandro Martinez but the Dutch side are yet to accept the offer.

Ajax are waiting to see if Arsenal make a rival bid as they look to stir up an auction between the Premier League sides.

The new offer is £5million more than United’s last proposal and is thought to be close to Ajax’s valuation — with the Dutch side mindful that the 24-year-old is desperate for a move to England.

Martinez – who has earned seven caps for Argentina – remains open to joining Arsenal if they meet Ajax’s valuation.

Meanwhile, United have been offered the chance to sign RB Leipzig striker Brian Brobbey.

The Dutch youth international came through Ajax’s academy but left on a free transfer to the German club last summer before being loaned back to the Johan Cruyff Arena in January.

It was a hugely successful spell for Brobbey, who scored seven goals in 11 Eredivisie games and impressed Erik ten Hag.

Leipzig want £17million for the 20-year-old, who could also make a permanent return to Ajax.

Finally, former United midfielder Paul Pogba has arrived in Turin ahead of signing his contract with Juventus.

The French international, 29, ended his six-year spell with the Red Devils this summer following the expiration of his contract.
