More than just a "bit worrying". I'm thinking what effect Danny's ever growing catalogue of injuries may eventually have on his ability to perform.
Searched his injury record for the last couple of seasons and if the info provided is true in terms of Danny's ability to stay injury free it makes for some pretty alarming reading.

Sturridge has missed 21 games for Liverpool due to injury since his move from Chelsea in January last year.
Despite his undoubted skill his injury record goes some way in part to perhaps explaining why Chelsea let him go in the first place.
