Brazilian great Rivaldo has urged Manchester United midfielder Fred to manage his temper better.
Fred was sent off in United's Champions League defeat to PSG.
Rivaldo told Betfair: "Fred's sending off arguably cost Manchester United the match against Paris Saint-Germain as the Red Devils looked capable of mounting a comeback and even going on to win.
"The Brazilian needs to learn to control his temper, especially in such a big match, and be patient.
"When you are chasing a game you might commit mistakes that will harm the team even more - as Fred did - so it's crucial to take a second, breathe in and breathe out, before going into risky challenges."
