Frank Lampard has expressed his belief that Chelsea made an error when they allowed striker Daniel Sturridge to leave Stamford Bridge for Premier League rivals Liverpool.

The 24-year-old joined the Reds in the winter of 2013 and has since flourished in partnership with Luis Suarez, leading Lampard to suggest that his old club may regret his sale.

He told The People: "I'm really pleased for Studge because, at Chelsea, I think he was a bit frustrated. He felt he could have played more. He felt the position he was playing in was one he wasn't happy with and he felt it was good for him to move.

"It was maybe not good business for Chelsea. It looks bad when you look back, but, at the time, you never know. Individually, for him, it was a good move. He has gone from strength to strength.

"For an English striker scoring as regularly as he has in the Premier League, it has been amazing and he is the sort of striker, the sort of attacking player, we have been crying out for with England."

Sturridge scored more Premier League goals than Demba Ba, Samuel Eto'o and Fernando Torres combined last season.
