Barcelona midfielder Xavi believes Manchester United's achievements over the past two decades should be a "reference point" for other clubs to try to emulate.
Xavi, 31, has helped create a lasting legacy at Barca, winning six La Liga titles, two Champions Leagues, one Copa del Rey and a FIFA World Club Championship during his 13-year career at Camp Nou.
At least someone can recognise quality.
In Sir Alex I Trust, United We Stand!
despite all the good thing Barca say about united out of respect the Catalans are still a better side and i go for 2-0 again
