Arsenal goalkeeper Emiliano Martinez joins Aston Villa for £20million keeping nine clean sheets in 23 games last season and helped the Gunners win the FA Cup.
Martinez shone for the Gunners at the end of last season after being forced to step up following a knee injury to No1 Bernd Leno.
The Argentina international helped Arsenal win a record 14th FA Cup, but has now joined Villa on a four-year deal as he goes after regular first-team football.
Villa boss Dean Smith said: “We are really pleased with the signing of our new goalkeeper Emiliano Martinez.
“We know how highly Arsenal rated him and we watched his outstanding performances last season in a trophy-winning top side.
“We moved for Emi when we saw the opportunity, as it is rare to be able to buy a top-class goalkeeper who hasn’t yet reached their peak age and who can therefore be a key player for our Club for the long term.”
