Former Chelsea midfielder Gus Poyet believes something is 'not there' with Romelu Lukaku as the striker continues to struggle at Stamford Bridge.
The Belgian was a substitute in Sunday's Carabao Cup defeat to Liverpool, though he did come off the bench to score a goal which was later ruled out for offside.
Since returning to the club in the summer from Italian giants Inter Milan, Lukaku has looked a shell of the player signed for £97.5million.
