The former Netherlands international watched the two sides in action in the Champions League on Wednesday, while taking to Twitter as part of Heineken's 'Share The Sofa' evening
Ruud Gullit watched the action as goals from Lionel Messi and Dani Alves, either side of a Vincent Kompany strike for the visitors, sealed Barca's passage to the last eight and the ex-AC Milan star tweeted his thoughts on the game for Heineken throughout the encounter, as part of their '#ShareTheSofa' night.
Goal compiled a list of our favourite tweets from the former Netherlands international during and after the game...
GULLIT ON BARCELONA
"Barcelona are proof that you need centre-backs who are decent on the ball."
"As usual Barcelona relying on Messi to do something to take the pressure off them. Got to get out of the habit."
"Barcelona can't rely on Messi to do everything, they need to work as a team."
GULLIT ON MANCHESTER CITY
"Looked like a penalty to me, but instead a red card for Zabaleta. That's where moaning gets you."
"People asking whether Pellegrini's ban made a difference. You do notice the coach."
"Man City haven't been outplayed, that goal was a silly mistake. City will be kicking themselves they didn't take their chances."
