Arsenal legend Nigel Winterburn says the club must receive an offer ‘in excess of £20-25 million’ for Emiliano Martinez to justify selling the goalkeeper this summer.

After over a decade at the club, struggling to break into the first team and being shipped out on six different loan spells, the 28-year-old finally got his first real opportunity last season when deputising for the injured Bernd Leno.

The Argentine produced a series of outstanding displays and stated a strong case to be Arsenal’s No.1.

However, Martinez has admitted that if he is reduced to a role on the bench again, he will be looking for a new club.

Aston Villa are one of the interested parties that can offer the stopper a starting berth, with Tom Heaton out injured for the start of the season.

Reports claim that the Gunners have decided to move Martinez on, with Aston Villa lining up a fresh bid after agreeing personal terms with the shot-stopper.
