Two things on this from me...
First, as long as Lee Hughes is playing for us and in good form he'll always be the subject of transfer rumour and speculation etc etc. I'm not going to worry about any of it until or if he goes.
Second, I think The Sun could be in line for a legal action of some sort if they're reporting that he has marriage strife and it is not true. I don't think they would find it worth their while to leave themselves open to any sort of even a hint of legal action for the sake of a few paragraphs if they weren't pretty sure what they were reporting isn't A. correct or B. something a person isn't going to take legal action over.
Having said all that I'm reverting back to the latter part of my first point... ie I'm going to enjoy Lee Hughes and his goals as long as he is in a Latics kit.
