"He's a hell of a loan signing on deadline day, someone like Lukaku," Bruce told BBC Sport. "I saw him playing for Belgium in midweek and he's going to be one hell of a player.
"Maybe the reason why he's gone there is Jose Mourinho has thought 'maybe Everton can go and get a few points off the big boys with him in their team'. That would be pretty shrewd really and I think they can."
Bruce's Hull are currently eighth in the Premier League with 11 points.
