Manchester City manager Manuel Pellegrini insists his players will never surround referees in an attempt to influence decisions.
The issue of player behaviour towards officials has been highlighted this week after Chelsea were widely criticised for their actions during the Champions League game against Paris St Germain on Wednesday.
One incident saw nine Chelsea players surround Dutch referee Bjorn Kuipers after a challenge by Zlatan Ibrahimovic on Oscar that resulted in the PSG striker's dismissal.
Pellegrini said: "You will never see a player of City surround the referee. I don't think that's the way this team is prepared to win.
"Maybe you can discuss with the referee about a decision, but just (for) one moment in the game."
Jordi Amat has become the second Spaniard to sign a Swansea contract extension in as many days.
Amat has followed the example of his countryman Angel Rangel by committing to a one-year extension which will keep him at the Liberty Stadium until 2018.
"I'm so happy because it's important to know the club has confidence and faith in me," Amat told the official club website.
Burnley have signed Norwegian midfielder Fredrik Ulvestad on a three-year deal.
The 22-year-old was a free agent after opting not to renew terms at home-town club Aalesunds FK and has put pen to paper following a spell training with the Clarets.
Burnley boss Sean Dyche will hope Ulvestad, who has made one appearance for the Norway national team, can adjust quickly to life in England and assist his side in their fight against relegation.
