Grealish and El Ghazi. They have said multiple times Grealish would take them if el ghazi is off the pitch.
Also zero chance next season Grealish doesn't take the majority of penites because he gets penalised for not taking them because his competition in Rashford takes about 6 a season and his competition for best player in the league Bruno Fernandes scored 9. (Obviously KDB as well, he also takes some pens but is bad at them).
