The winger joined on a season-long loan deal from Manchester City.And Moyes hinted Grealish could play from the off.He added: “Grealish looks the same, big calves.“You need to turn up and find out whether he starts. That’s what everyone needs to do.“I think Jack can play in several positions, I think he can play midfield as well.“He doesn’t give the ball away very often, but my aim is to get Jack in positions where he will get goals and assists for us.“It’s a big challenge for Jack as well. I’m looking forward to see how he responds to it.”
