First time I've heard of anything like that to be honest - I've always seen/heard that he's actually very professional and I doubt Moyes or Martinez would allow anything less.
Where did that story come from?
Mate of mine works at the facility, in the capacity of booking in whole teams/individual players. Most recent visitors being Milan and Real Madrid, it really is different class. Man UTD were over last winter and Carrington is getting a refit on the back of the visit. There is a slim chance Everton will come out here, but only if we're knocked out tonight, so hopefully not.
The driver laid on for them for the 8-10 days they were here was with them pretty much the whole time they were not in hotel room, he reported the antics.
We've been through this before. Even if what you are saying is true, there is no reason to think it wasn't club sanctioned and probably club endorsed to send Gibson away to let his hair down after months of mind-numbing rehab.
With regards to the latest news that Gibson is doing a 'mini pre-season', it must mean he's had setbacks after being reported as being close to a return and was 50/50 for games a month ago. He's been out for two months total and is now doing this 'mini pre-season'. Who knows when he'll return. Maybe February? 3 more weeks of this 'mini pre-season' seems enough. But then Martinez might as well just call it a 'pre-season'. In fact in total it's probably longer than a regular pre-season so he should really be calling it a 'maxi pre-season'.
100% club sanctioned, use of facility was free but hotels/flights for both paid by EFC. His 'trainer' had EFC kit that was so small (due his his bulk) it looked comical. I'm sure the idea was to let his hair down as you say, but I doubt to the degree it was
I would LOVE to see him back, fit and available because he's a real asset. I just don't believe it will happen. Fingers crossed though, sooner a fully fit Gibson than a fully fit Osman.
