For the FA Cup draw with QPR, Long insists he enjoyed playing alongside Lukaku as the pair featured together in Steve Clarke's starting line-up for only the second time this season.
"It was enjoyable," Long told the WBA website.
"Rom is a big strong lad who puts himself about.
"He worked hard in the first half and, with the formation they played, it was difficult to attack because they had three at the back and two holding midfielders.
"It was more or less five versus two so it was difficult to get on the ball.
"But when they changed their formation in the second half they got into the game more and Rom had a few chances to score - and brought a few people into the game as well.
"It was enjoyable."
