The former Liverpool and Inter boss has voiced his opinion that the Catalans are a great team, but stressed that they\'re not at the same level as the illustrious Rossoneri side yet.Former Liverpool manager Rafa Benitez feels that Barcelona are not the best team ever as he believes that the AC Milan of Arrigo Sacchi were even better than the Catalans\' current squad.Barcelona have won two Champions League trophies in the past three years and are once again among the favourites to win the competition this season.However, Benitez is of the opinion that the Milan of the late 80s and early 90s were on another level.\"Are Barcelona the best team I have seen in my lifetime? To be fair I was an admirer of AC Milan when they were playing with [Marco] van Basten and [Ruud] Gullit and all these players, with [Arrigo] Sacchi as the manager,\" Benitez said to fifa.com.\"They were doing really well, they were very dominant at that time. Barcelona have been more or less the same, and you can see now Bayern Munich or sometimes [Manchester] United or Real Madrid can challenge.\"I remember Real Madrid was a fantastic team at the time and they couldn’t do anything against Milan so it was a big difference. But Barcelona are a great team to watch.\"Barcelona take on Milan in the second leg of their Champions League quarter-final at Camp Nou on Tuesday. The first leg between both sides finished 0-0 at San Siro.
