Ronaldo spoke to the distraught United players after the match and made special mention of 39-year-old Ryan Giggs, for whom it was his 1,000th professional game.
"I went into the dressing room to speak to all the players, the coach, the president, to the Glazers," said Ronaldo.
"I spoke with Giggsy and he's an incredible player, still fit and still playing in these kind of games. He is the flag of this club and I'm happy for him. I think he's going to finish when he's 50!"
