Manchester United have joined Arsenal's interest for Ajax defender Lisandro Martinez.

The Gunners have had a £25million bid rejected for the Argentine ace.

And now United have emerged as rivals to Arsenal for Martinez's signature, says Sky Sports.

Boss Erik ten Hag has been asked to be kept in the loop with Martinez's situation.

Martinez has spent the last three seasons at Ajax, winning two Dutch titles under Ten Hag.

And now it seems the United gaffer is keen on a reunion with the 24-year-old centre-back.
