The whole lifestyle thing is dependant on the player in question and his nationality isn't really a good indicator imo.
Theres two choices for rich folk in manchester.
1.
You can live in the city centre in an amazing penthouse and be a 5 minute walk from every type of restaurant you could think of, any type of shop you can think of and see any type of event (MEN arena) - Guardiola is in this boat and he prefers Manchester over Munich apparently; which he said was surprising at first.
2.
You can also be rich in manchester and live out of the city in areas like Wilmslow, alderley edge, hale barns etc which are nice little villages on their own but there isn't that much to do around there although the house you will be living in will be one of the most up to date, desirable mansions you can buy in the world.
Most footballers who have settled here have picked number 2 but number 1 is becoming more popular with the growth of residential developments in manchester city centre. Alot of recent city staff have chosen to reside in the city and I reckon united the same, although traditionally i think the club (fergie) would've preferred the players to settle down in the quiet leafy suburbs with their family.
All in all manchester is a good destination for the rich. The weather obviously isn't great but a few years of living in a cooler wetter climate isn't the end of the world is it? Everyone is different. I wouldn't mind living in Pripyat for a few yeara if a company was willing to double my current wages for example.
