Jimmy Bullard insists his former team need to strengthen if they are to stay in the Premier League.
The Tigers won promotion to the top flight after finishing second in the Npower Championship last season, beating Watford to the position on the final day of the season.
Having been relegated from the Premier League with the club in 2010, Bullard, who was forced to retire in October due to persistent knee trouble, feels goals are sure to be the key to survival at the KC Stadium.
"You need to score goals in the Premier League don't you, so you need proper world class strikers. No disrespect to who they've got - they've got some good players - but you need world elite if you want to stay in that division," Bullard told GiveMeSport in an exclusive interview.
Steve Bruce's side struggled for goals last season, with top scorer Robert Koren, a midfielder, only hitting the back of the net nine times for the Tigers.
Bullard's time at Hull was blighted by injury after rupturing cruciate knee ligaments on his debut after a £5m move from Fulham in Janaury 2009, the second time he'd suffered the injury in just three years.
Now trying to forge a career as a pro-golfer, he's delighted the club have returned to the Premier League, despite his own controversial exit from the club in 2011.
"They've got a good manager - they'll need to buy some players, I imagine, to stay in the Premier League - but they've got a chance. The spine is key, and it's going to be a big summer for sure. I'm delighted they are there though because it's a great football club," he added.
