Mostovoi's exclusion from Euro 2004's national squad happened after the 0–1 group stage loss to Spain. Supposedly, the player talked with the media after the match and gave an interview saying that Yartsev was not a good coach and did not understand anything. This was later proven false, after Mostovoi gave another interview and explained he merely said that Yartsev overworked the players during practice, so they didn't have the necessary energy to play well in matches. All in all, group morale dropped after the incident, and Russia lost the second game to hosts Portugal.
