Surgeons are said to be “thrilled” after Aston Villa goalkeeper Brad Guzan became the recipient of the world’s first full head transplant.

Guzan himself was unavailable for comment since he no longer has a working mouth, but sources close to the American say that he is delighted with the results.

Martin O’Neill is said to be monitoring the situation and is considering recommending a similar operation for Curtis Davies. Experts believe that using a helium balloon will improve his ability in the air.
