Henderson told liverpoolfc.tv that he expects to be fit and firing when his debut Anfield term comes around and insist he will not use burn out as an excuse.

"Yes I've played a lot, but I've still got lots to give, still got energy. We are young and want to play football and can achieve something special for our country."
