“I'd have to go with [Steven] Fletcher when he was at Wolves, he was different class,” the 25-year-old centre-back told Sky Sports. “Benik [Afobe] and [Bakary] Sako are up there as well so it's pretty tight between those.
"I'll always go with forwards because they're the ones who always give me a torrid time in training.”
Steven Fletcher joined Wolves from Burnley in the summer of 2010 and was on their books until 2012.
The 28-year-old Scotland international striker was superb during his time at Wolves and earned the move to Premier League outfit Sunderland in the summer of 2012.
The former Hibernian star, though, has struggled at the Black Cats and has proven to be a largely average striker in the Premier League.
Benik Afobe joined Wolves from Premier League giants Arsenal in January 2015.
The 22-year-old striker has already proven to be one of the best young players in the Championship.
Afobe has scored six goals and has created 13 chances in 15 Championship appearances so far this campaign.
The former Arsenal prospect found the net 13 times and created 19 chances in 21 league matches for Wolves last season.
Bakary Sako joined Wolves from French club Saint-Etienne in the summer of 2012.
The Mali international, who can play as an attacking midfielder or as a striker, was one of the best players for the team in the following three years.
Sako left the Championship side for Crystal Palace in the summer transfer window and has proven to be a good acquisition for the Premier League outfit.
The 27-year-old has scored two goals and has created seven chances in eight league appearances for Palace so far this campaign.
