Just to avoid further conflict when he eventually starts playing in the Premiership, how are we going to pronounce his surname?
For example, we could call him "Kay-hill", as per Tim Cahill at Everton.
Or we could call him "Car-hill", as per my attractive 17-year-old friend Helen. Bearing in mind that he hails from Sheffield, meaning it will have a Yorkshire pronunciation, and Miss Cahill comes from North Yorkshire..
My vote therefore goes with Car-hill
