Henderson has been on loan at Sheffield United for the last year-and-a-half, and has won plaudits for his displays for the Blades.

"There's talk because David de Gea made a mistake at the weekend that he should be back as No.1 at United but I don't think it's as straightforward and simple as that.
"But for me, De Gea is still a fantastic goalkeeper and some of the saves he makes, he's one of the best."
