West Brom boss Clarke throws down gauntlet to Lukaku
Lukaku recently grabbed the chance to prove himself in the Barclays Premier League by making a season-long loan switch to Albion, before this week hitting out at his parent club and branding last season as a waste of time.
"He's certainly hungry, I know that," said Clarke, who is in his first permanent managerial post.
"But he's got a clean slate this year. He's one of a number of strikers competing for a place in my team and I'm hoping that at the end of this year he's not complaining about anything."
