(CNN) -- Manchester United manager Alex Ferguson believes governing body UEFA should consider a system which will enable clubs to appeal against bookings.
Ferguson was unhappy with the yellow card shown by Portuguese referee Olegario Benquerenca to Darren Fletcher in the English Premier League side's 3-3 draw with CSKA Moscow during their Champions League clash at Old Trafford.
Television replays appeared to suggest the United midfielder seemed to be tripped but Fletcher was instead booked by Benquerenca which left Ferguson calling for a method to appeal.
"I can't believe the decision. It's one of the worst I've seen in my lifetime and there's not a thing we can do about it unfortunately," Ferguson said.
"You can maybe understand it [the fact you can't appeal yellow cards] in domestic football because it would clog up the system if everyone appealed bookings.
"But the situation in Europe is different - three bookings could mean you end up missing a Champions League final for example, just as Darren did last season when he was very unfortunate yet again. And the booking tonight could lead to him missing a really important game this season.
"It's something that UEFA should look at and the referee should be open about it. He's made a bad mistake - we all make mistakes in games and he should be big enough to say he's made a mistake and forget the booking."
It is the second time Fletcher in European competition that Fletcher has been the subject of a controversial brush with officials.
Last season he missed the Champions league final against Barcelona in Rome after he was sent-off for a professional foul in the semi-final against Arsenal despite playing the ball.
Despite his irritation with the decision Ferguson was pleased the with character of his side who fought back from 3-1 down to secure qualification to the last 16.
The English champions produced a sterling comeback in the Group B clash as Paul Scholes scored with a header in the 86th minute from a Gary Neville free kick and Antonio Valencia equalized in injury time with a shot which took a wicked deflection.
Alan Dzagoev had put CSKA ahead in the 25th minute but Michael Owen leveled four minutes later for United with a typical opportunist effort.
Milos Krasnic made it 2-1 for the visitors as he eluded the United offside trap before halftime to score smartly on the turn.
Aleksei Berezutski headed the third at the start of the second half as he took advantage of more slack home defending.
It prompted a furious home response, with new father Wayne Rooney drafted off the bench to lead the charge.
"We were absolutely fantastic in terms of our desire to win the match and were unlucky at times in the game," Ferguson told the club's Web site.
"Their goalkeeper made some fantastic saves, we hit the post and missed a lot of other chances. And we also had a stonewall penalty turned down.
"But we didn't make it easy for ourselves and it became an uphill fight. That's maybe not a bad thing though because it's a reminder that when you leave yourself open in European football it can be very dangerous."
