Emiliano Martínez has perhaps been the signing of the season outside of the 'Big Six'. The Argentine put in impressive performances at Arsenal towards the back end of last season, where he helped win them an FA Cup.
After this, along with Aston Villa's goalkeeper issues, the club signed him from Arsenal where he made just 15 league appearances in 10 years. Now, Martínez has established himself as one of the best keepers in the league and as the favourite to make the PFA Team of the Year, in the eyes of many.
As of now, the keeper has kept 14 clean sheets across 30 appearances for Villa, which is only bettered by the league leaders Manchester City and the newly-formed threat of Chelsea under Thomas Tuchel.
Martínez has been exceptional all year long, and whilst Rui Patricio deserves acknowledgement for his services down the years, the Villa man is the best around right now outside of the 'Big Six'.
