The Belgium international has returned to goalscoring ways after ending a drought that had lasted since September, while the Aston Villa captain also praised Andreas Weimann
The 23-year-old, who led the Villans' scoring charts last season, had endured an indifferent campaign this term and struggled in front of goal following a series of injury problems.
But the former Genk frontman netted against Arsenal just over a week ago before scoring the second goal as Paul Lambert's men drew 2-2 with Liverpool on Saturday.

"It is good that Christian is scoring again," the Dutch defender told the club's official website.
"It has not been easy for him the last few months but he scored against Arsenal and he scored again on Saturday so it is starting to come to him again now.
"It is really important for the team as well."
The encounter at Anfield also saw forward Andreas Weimann end his own barren streak in front of goal, having not registered in the league since the 3-2 victory over Manchester City in September.
Vlaar is now hopeful the 22-year-old will be boosted by the goal, while also praising the impact of Gabriel Agbonlahor, who played a part in both of Villa's goals before departing after sustaining a knock.
He added: "I think Andi (Weimann) scoring was also very important for him and for the team.
"It has not been an easy season for him as well, so I hope that scoring at Anfield gives him a real boost to carry on.
"I think the two crosses from Gabby were brilliant. It's just a pity that he had to go off with an injury."
