Living in a Capital city is completely different, a Pro rugby player is more or less training, watching rugby videos getting treatment etc etc, and they do not get out that often, they go to bed early get up early and spend most of the days with their other team members in the Stadium it also depends on the atmosphere in that particular club, quite often you have the groups French, Islanders Aussies and Kiwis and the Brits, these fractions can isolate certain players if they are of the more quieter nature and therefore the homesick sindrome can easily happen. We had one player at Montpellier when he arrived had the same problems but after a 3 day mini altitude camp where there was lots of sillyness , he found his place and is now fine. Not all the clubs look into how some foreign players adapt to their own situations and this does cause problemsSexton will not be the last to feel lonely, France is not necessary for everyone, the French are very different sometime exasperating and arrogant but that is their way and often you have to change in intergrate, i have lived here for years and love the country and the people, love it just as it is, but its not for everyone.
