The Spaniard has impressed for Celta since joining in 2013, hitting 19 goals in 45 games for the La Liga club.
Grande has revealed that Nolito's form will lead to a call-up to the next Spain squad.
"Nolito is tremendous. The next game is in Vigo and we are planning to call him," AS quotes Grande saying.
Nolito, who was linked with a move to Premier League side Everton in the summer, already has five goals in eight games this season.
