England and Chelsea legend Frank Lampard admits Chelsea made a mistake selling Daniel Sturridge to Liverpool.

Sturridge moved to Anfield in January 2013 for a fee believed to be around £12m. Since then Sturridge has scored 31 goals in just 43 league appearances for the Merseyside club. Samuel Eto’o, Fernando Torres and Demba Ba scored only 19 goals among themselves in the Premier League last season, while Sturridge alone managed to score 21 league goals.

Daniel Sturridge played a key role for Liverpool as they fell short of the title by just two points. He has been selected for the England World Cup squad and is expected to lead the England attack. Lampard believes Sturridge was played out of position at Chelsea and it was “bad business”.

Lampard said: “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.

“I think he does get the credit he deserves now, but with what Luis Suarez does alongside him at Liverpool, maybe that takes the edge off the praise.

“But, 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.

“He is someone who can make something out of nothing, as he did when he scored against Peru last week, so he has emerged and deserves to be on this stage.

“I think he has got that little strain in him where he always believes in himself. It’s not easy when you’re a young boy and you’re not playing so much. You can drop your head down.

“But, when he has played, Studge has got that inner-belief and no wonder, because he is one of the sharpest players I have seen off the mark, with his quick feet around the box and he gets his shots away, he is very difficult to defend against. I think he is comfortable at Liverpool.

“At Chelsea and struggling a bit to get in the team and then he goes and he has a lot of belief in him there at Liverpool, you can see Brendan Rodgers really trusts in him, he started scoring and he hasn’t stopped.”

Lampard, 35, who left Stamford Bridge last week after 13 years is expected to join Spanish striker David Villa at New York Major League soccer club part-owned by Manchester City.
