Emile Heskey believes Liverpool lack the squad depth to challenge Manchester City for the Premier League title.

Former Reds striker Heskey says Jurgen Klopp's side will struggle if one of Roberto Firmino, Sadio Mane or Mohamed Salah don't score.

"It's a tall order because at this moment in time City have the best squad in terms of depth," Heskey told Omnisport.

"If you take certain players out of City they've always got someone who can step in and do a specific job, the way the manager wants him to do it.

"Liverpool, if you take Salah, Mane or Firmino out, it's not quite the same, whereas City have a better blend."
