Manchester City forward Grealish, who was excluded from England's Euro 2024 squad under former head coach Gareth Southgate, was brought back into the team by interim manager Lee Carsley last week for upcoming fixtures against Ireland and Finland.
Robinson, who went in the opposite direction as Grealish in playing for England's youth teams before switching to Ireland, expected the 28-year-old to handle the hot reception.
"I think he'll be getting ready for a bit of abuse but that's part of it, it's part of the game," Robinson, Grealish's former teammate at Aston Villa, said on Tuesday.
"He's old enough and with being a senior player now, that stuff's going to come.
"I'd be surprised if he doesn't because I think he gets booed anywhere he goes anyway, even in England."
