Spain coach Luis Aragones insists his argument with Sergio Ramos during training on Friday was of little consequence.
Carlos Marchena had to pull his defensive colleague to one side after Ramos had appeared to take issue with something Aragones said.
However, the veteran manager has played down the incident, saying: "We were talking about things that affected the team and he expressed his opinion, that's all.
"There is an extraordinary unity in this group. The thing is, because everything is going so smoothly, things like this get picked up when they are not important."
Earlier in the week Aragones had defended Ramos, who had been criticised in the media for some poor displays, saying: "There are certain codes of football Sergio has to understand.
The better player you are, the more discipline you have to have in every sense.
"He is a great person but at times he has done some things he shouldn't and we've talked about it."
