Lisandro Martinez could be denied dream squad number at Manchester United

Even though Lisandro Martinez's dream shirt number is available at Manchester United, he may not be able to take it due to another potential arrival.

United closed in on making Martinez their third signing of the summer when they announced on Sunday that a £46.8million, rising to £55.3m, deal had been struck for the versatile defender with Ajax.

The Argentine follows the signing of left-back Tyrell Malacia and the free transfer of elegant playmaker Christian Eriksen as Erik ten Hag's squad finally begins to take shape. The new manager was keen to bolster his defensive options and after Jurrien Timber made it clear he was staying at Ajax, attention turned to his teammate instead.
