Didier Drogba wasn't happy with the decisions made by referee Tom Ovrebo during the Champions League semi-final on Wednesday.
At the final whistle Didier Drogba marched onto the field where he confronted the ref. He was given a yellow card but despite the punishment he continued to talk to Ovrebo while being held back.
So that got us thinking, should the referee's decision always be final?
Do we need to have one person who makes the decision, or should there be other people who get involved?
Is it right to argue with the referee if you don't agree with him?

"I think they should because they are usually fair and just. Also, it's quicker to reach a decision with just the one person."
Emily, 11, Lancashire, England
"I think it's OK for the referee to have the final say, but not ALWAYS. Chelsea were right to be angry, the referee missed most things that happened in the game."
Rachel, 10, Belfast, Northern Ireland
"Well, I know it's their job to take control but sometimes they do go a bit OTT."
Amy, 12, Bournemouth, England
"I think the ref should always have the final say because if not then there would be no point having refs."
Liam, 10, Derby, England
"I don't think the ref should always have the final say because he could get it wrong and he should be able to see the replay."
David, 9, Surrey, England
"Yes, they should, but they make some bad decisions."
Lottie, 13, Dundee, Scotland
"No the ref shouldn't have the final say because lots of the time they get it wrong. Chelsea were right to be angry."
Gwenllian, 11, Wales
"They should have a third umpire like they have in cricket so then they can look back and see what happened."
Alliya, 13, West Yorkshire, England
"I think that there should be video referees so they can see the video afterwards and make sure the ref makes the correct decision."
James, 12, Kent, England
"I don't think the referee should have the final say. I think all referees should have to check (like in rugby) with the video evidence before giving any cards or penalties."
Abbie, 13, Sheffield, England
"The referee is in charge of the football match so I guess the players have got to listen to the referee. But it is clear that the referees sometimes makes the wrong decisions."
Ashley, 12, Lincolnshire, England
"I think that he should've been more respectful toward the ref, but I think he was right."
Saamiya, 13, London, England
"No they shouldn't. It is the players' game as well so they should have a say and Didier Drogba was right to shout at the ref - I would have."
Daniel, 14, Scotland
"I think that referees should think before they act."
Josh, 9, London, England
"Referees should always have the final say. If there were no referees then football would not be a fair game. The referee made mistakes in the Chelsea game, but the score can't change now."
Harry, 12, Swindon, England
"I feel that the decision shouldn't be made by just one person. Even though the referee controls the game, it doesn't mean that he can make all the decisions he wants to. He was biased against Chelsea."
Bharathy, 14, Essex, England
"My dad says grown men who get a lot of money for playing a game instead of working should not make a fuss."
Bobby, 12, York, England
"I think that there should be at least three referees to decide. There were definitely two penalties and I couldn't believe Chelsea weren't even given one. Chelsea were the best team and were way better in in the match. The reason they didn't go to the final was because of the wrong decisions the referee made."
Mariam, 13, London, England
"I think the referee should have a look at the video replay and see the mistakes he made. I am a huge Chelsea supporter and think it's not fair."
Rea, 12, London, England
"Drogba was being very stupid for all that shouting. The referee was very good actually."
Jim, 12, Luton, England
"I think there should be a replay between the two teams because it was not a fair match."
Nathan, 12 (nearly 13), Sheffield
"Uefa should be taking action for this absolutely rubbish ref. It was 1-1 and it should have been 5-1!!!!!!!!!!!!"
Toby, 11, Stokenchurch
"I think it shouldn't be final. They should see some footage if they are unsure about the decision."
Andy, 13, UK
"Chelsea are a bunch of sore losers. Manchester United will beat Barcelona."
Calum, 14, Middlesbrough
"I think Drogba should get a bad fine and he should be banned from playing for a year! I still support Chelsea though and I love Ashley Cole."
Mara, 11, Barnet, England
"No, I think there should be a video replay shown, just like in cricket, to ensure the decision is right."
Mori, 14, Watford, England
"I'm a West Ham supporter and I was watching the match, and I'm not being biased or anything but Didier Drogba is right. The referee did make a bad decision and it was unfair! He shouldn't be banned at all for something bad that he didn't do!!!"
Milly, 13, Ilford, England
"He (Didier Drogba) was right to confront the ref as he and the team had unfair decisions made against Chelsea, which in turn got them knocked out."
Jacques, 9, London, England
"I think the referee was intimidated by Chelsea. Yes, I don't watch football, and I support Chelsea, because my family does, but I think the referee was too harsh, and was over-intimidated. Didier and Ballack had the right to quarrel over the results. Chelsea deserved it more."
Riordan, 12, Huntingdon. England
"Drogba is a very bad role model for all those kids eager to get into football. This season is supposed to be the start of the respect season to start a game of football enjoyable by everyone."
Joe, 14, Northampton, England
"I think that's not fair, because it's not just about what the referee thinks, there are other people too. But I do think that that Drogba could've been a little more respectful to the ref."
Iyath, 11, Maldives
"Drogba has disgraced Chelsea and should be given a six game ban in my opinion."
Adam, 10, Stockport, England
"The referee should lose his job and Drogba should get a pay rise for sticking up for what he believes in."
Lydia, seven, West Bromwich
"Yes the referee's decision should be final . The referee is in charge of the match and he should have the final say. Yes there should be one person making the decision."
Charlotte, 14, Melton Mowbray, England
"Drogba overreacted I think. He should be banned for two weeks with no pay and the ref deserves more respect."
Vijay, 11, Surrey, England
"I thinks Drogba is a bad player and the referee should not have given him a yellow card but a red card. Also Drogba should not be allowed to play for three months until the next season starts."
