The on-loan Chelsea ace has won the club's Player of the Month for January.
"I wasn't sure we would be this high in the league but after three games I knew we were capable and I knew it was going to be good for me," Lukaku told the WBA website.
"The league is long and we have 12 games to go.
"Everything can change and now it's up to us.
"We are in a good position and the European spots are right in front of us."
